Introduction
One of the most influential theories of justice in planning theory and practice has been, without doubt, that of John Rawls. Basta (2016: 191) observes: “In the past two decades, Rawls’s Theory gave rise to a dedicated planning literature”. And Winkler and Duminy (2016: 119) note: “Rawlsian philosophy […] remains a key influence on planning theory and ethics”. The very idea of the just city is indebted to Rawls’s view. I obviously do not want to say that Rawls was the only philosopher who influenced the notion of the “just city” (other authors – both philosophers and economists – were undoubtedly crucial in this regard, e.g. Sen, 1987; Young, 1990; Nussbaum, 2006); I am simply underscoring that his influence was indisputably strong.
However, the way in which Rawlsian theory of justice has been imported into planning often seems debatable. This article aims to discuss this aspect critically. The objective is not merely to discuss certain planning approaches inspired by Rawls; it is also to investigate, in more general terms, what meaning and role (any theory of) justice could and should have for planning and urban policies. In revisiting John Rawls’s view, the article is structured around two points, which will be considered in sequence: first, a critical discussion on how Rawls’s theory of justice has been generally applied to urban policies and planning; second, an exploration of an alternative way to interpret and apply certain Rawlsian insights (often undervalued) in this field.
The article is not intended to defend and recommend Rawls’s normative theory as a whole (i.e. in its entirety), but to evidence certain Rawlsian contributions of a general nature that are particularly important. Nor is it the aim of this article to contribute directly to the development of a specific substantive idea of the just city (as in Fainstein, 2010); instead, it is to highlight fundamental methodological and analytical caveats that are crucial in this regard. Rather than a theory of the just city, this article develops a meta-theory of the just city: that is, an approach specifying precautions and conditions for any coherent and convincing just city theory (the term “meta-theory of justice” is used here in a way similar to – even if not identical with – Hockett, 2004). Therefore, the article aims to contribute to the debate on normative planning theory (e.g. Klosterman, 1978; Harper and Stein, 1992; Watson, 2002), although from a particular point of view.
Rawlsian approaches in planning: The prevalent view
As well known, Rawls’s theory (1971, 1993 and 2001) is focused on two hierarchically ordered principles of justice. The first principle upholds a set of fundamental freedoms for all. The second principle, particularly that part of it known as the difference principle, states that social and economic inequalities are to be to the greatest benefit of the least advantaged members of society. Rawls imagines that these two principles are the principles that appropriately characterised parties would have chosen (under the so-called “veil of ignorance”) in the famous original position: that is, a hypothetical pre-constitutional situation.
In the planning literature, the Rawlsian principles of justice, especially the difference principle, have often been interpreted as criteria with which to directly orient and design local urban policies and plans. A large number of the planning theorists and urban policy analysts that have adopted a Rawlsian approach maintain that the difference principle 1 should be applied directly to individual local policies and plans (see e.g. Beatley, 1988, 1991; Kiernan, 1983; Marlin, 1995; McConnell, 1981, 1995; Lake, 2018; Adegeye and Coetzee, 2019; Cohen and Allweil, 2020; Garrison, 2021; Feitosa et al., 2021; Mensah and Tucker-Simmons, 2021). Also in transport planning studies, the discussion on Rawls often assumes that his principles – and, again, especially the difference principle – can be applied to local policies and plans (see e.g. Khisty, 1996; Meyer de Freitas et al. 2017; Pereira, 2018, 2019; Hickman, 2019; see moreover the comparison among different ethical principles in transport issues by Pereira et al., 2016; France-Mensah et al., 2019; Creutzig et al., 2020; Adli and Chowdhury, 2021; Lewis et al., 2021).
For instance, Kiernan (1983), after citing Rawls’s difference principle and asking how, concretely, this normative principle might be applied in the day-to-day activities of planning practitioners, suggests the following. The planner’s main task is to state explicitly who benefits and who loses from “whatever planning proposal is under consideration” (Kiernan, 1983: 83). Having done this, “planners ought to practise the politics of positive discrimination […]. The first test of any planning proposal would be the extent to which it contributed to the alleviation of social and economic disparity. Planners would consciously structure their own proposals and their adjudication of those emanating from the private sector according to this principle […]. What is being advocated is the systematic and disproportionate allocation of the benefits of future planning proposals to ensure that both the absolute and the relative position of the disadvantaged is improved” (Kiernan, 1983: 83).
Also McConnell (1981: 192), in his attempt to apply the Rawlsian perspective to planning issues, states that “planning decisions should be to the greatest benefit of the least advantaged”. And he adds that this should also be an aim with redevelopment projects: “The application of the principles of justice will mean that restructuring of urban areas […] should be for the advantage of the most disadvantaged people first” (McConnell, 1981: 192). In short, “John Rawls’s principles of social justice can offer planning officers and politicians guidance in their decision-making” (McConnell, 1981: 174). The same view is reasserted in McConnell (1995: 43): “The principles of planning for justice should […] form the decision-making criteria in planning and in implementation of plans. […] Accepting the principle of liberty, the aim will be to follow Rawls’s second principle so that planning decisions should be to the greatest benefit to the least advantaged […]”.
A well-known attempt to adopt a Rawlsian approach in urban planning practice is represented by the Cleveland Policy Planning Report (Cleveland City Planning Commission, 1975). The report assumes equity as the primary guide for all urban policies and plans, and explains: equity requires that responsible local governments “give priority attention to the goal of promoting a wider range of choices for those Cleveland residents who have few, if any, choices” (Cleveland City Planning Commission, 1975: 9; see also 7, 13, 17). This idea of equity is justified (as the report stresses, “by reason”: Cleveland City Planning Commission, 1975: 11-12) by explicitly referring to Rawls’s principles of justice. 2
In conclusion, not all, 3 but a very large number, of those authors adopting a Rawlsian approach in planning have suggested applying the difference principle directly to individual urban policies and plans. As we will see in the next section, this is quite different from Rawls’s own approach. All this has occurred partly because Rawls’s theory has been misinterpreted, but also because many normative approaches to planning assume, more or less implicitly, a questionable allocative idea of (urban) justice. Let us explore this issue in detail.
Building blocks for an alternative view. Two crucial components of Rawls’s real position
The basic structure of society and background (procedural) justice
In reconsidering Rawls’s own perspective, two main notions are crucial: (i) the idea of the “basic structure of society” and (ii) the idea of “background procedural justice”. These two notions are the core of Rawls’s view. Even if they are interconnected, each of them has its own distinctive features and implications.
Let us start by considering the idea of the basic structure.
If the question concerns what the subject of a theory of justice could be, there are three main alternatives (Bedau, 1978): (i) persons (e.g. their characters and/or their acts); (ii) patterns of possession (in terms of things, goods, resources, distributed among persons); (iii) institutions (especially public institutions).
Rawls defends a particular version of the third option, and this makes him uniquely innovative in a certain tradition of political philosophy (Barry, 1995: 214; Audard, 2007: 60-61). According to Rawls, the primary and specific subject of justice is actually the “basic structure of society”: that is, the way in which the major social institutions assign fundamental rights and duties, regulating the division of advantages that arises from social cooperation over time (Rawls, 1971: 7, 1993: 257-288 and 2001: 10-12, 52-57). The basic structure constitutes the social framework within which individuals’ and groups’ activities occur. 4
Rawls clearly states that his two principles must be applied primarily to the basic structure of society. In other words, they are not intended to guide everyday policies directly (e.g. urban policies and plans) but to design the basic institutional framework. The two principles of justice assess the basic structure by considering how it regulates accessibility to primary goods: that is, the all-purpose means necessary to enable citizens to pursue their different specific conceptions of good. Principles for the basic structure constrain and limit, but do not determine, the suitable principles for post-constitutional choices. In short, there is no attempt to define first principles that apply equally to all subjects and situations (Rawls, 1993: 258). To simplify, we can say that Rawls’s theory of justice is primarily a theory of constitutional design (Moore, 1979). In conclusion, “the difference principle is not a principle of public policy” (Brown, 2012: 628); it is a super-rule, a meta-normative principle. 5
Let us now consider the notion of background (procedural) justice
According to Rawls, distributive shares are a matter of procedural justice. “The intuitive idea is to design the social system so that the outcome is just whatever it happens to be” (Rawls, 1971: 84-85). In other words, procedural justice obtains when there is no independent criterion for a valid result: “instead, there is a correct or fair procedure such that the outcome is likewise correct or fair, whatever it is, provided that the procedure has been properly followed” (Rawls, 1971: 86). This point is stressed in many other subsequent works. For instance, in Rawls (2001: 54): “When everyone follows the publicly recognised rules of cooperation, the particular distribution that results is acceptable as just whatever that distribution turns out to be […]. This allows us to abstract from the enormous complexities of the innumerable transactions of daily life and frees us from having to keep track of the changing relative positions of particular individuals”.
6
According to the idea of procedural justice, no distribution can therefore be assessed in isolation from the background system of which it is the actual outcome, and from what citizens have done in good faith in the light of established expectations (Rawls, 1971: 88). In this case, any state of affairs is acceptable if (and only if): (i) the state in question is the result of a procedure that is fair, (ii) the procedure has been actually carried out (Dupuy, 1988: 69). Note the importance of the latter clause. It would be illegitimate to claim that a particular state of affairs, which is to our advantage, is the just one because it could have been obtained by adopting a fair procedure. It is an unavoidable condition that the procedure had actually been carried out (Dupuy, 1988: 69).
The Rawlsian distinction between “procedural” justice and, so to speak, “non-procedural” justice is therefore different from the one in normal usage (Ceva, 2012; Meshelski, 2016), which is typical also in planning theory and urban studies (see e.g. the debate on “procedural justice” deemed typical of communicative planning approaches: Nylund, 2014; Fainstein, 2017). In planning theory, the distinction is usually interpreted as a distinction between formal justice of processes (i.e. who takes part in voting procedures and public and participatory debates, and how they do so) and substantive justice of outcomes (i.e. who finally obtains what). Fainstein (2005, 2009) highlights how we should have both. Innes and Booher (2015) observe how we cannot but have both: processes and outcomes in this sense are always in some way connected in each normative approach to planning.
In Rawls (1971: 517; 2001: 50), the distinction between non-procedural and procedural justice is, by contrast, a more interesting and original distinction not so much between substantive outcomes and formal processes as between allocative justice and background justice.
Allocative justice
Allocative justice applies to a given amount of goods to be divided among various real individuals with known preferences. Here justice becomes a sort of efficiency (i.e. maximization of the output effects of the apportionment of a fixed amount of specific items to specific persons).
Background justice
Background justice instead concerns the framework institutions that grant better conditions across time to the relevant “representative person”. This last is a crucial point which is often overlooked. As Rawls (1971: 64) states, when the principles of justice – e.g. the difference principle – mention “persons” the reference is always to “representative persons”. (The idea of a representative person is a handy way to refer to a group that has been already specified in some way: Rawls, 2001: 69-70). Observing that the difference principle requires that persons benefit from permissible inequalities in the basic structure, Rawls (1971: 64) specifies that this means that it must be reasonable for relevant representative person to prefer a life prospect with these inequalities to a life prospect without them. The inequalities to which the difference principle appropriately applies are therefore disparities in citizens’ reasonable expectations in terms of primary goods over a complete life (Rawls, 2001: 59). Thus, the difference principle is not supposed to be sensitive – or responsive – to the special and specific needs of particular individuals (Schaller, 1998: 370-371). 7 The fact that defining representative persons for various fractions of contemporary societies is not easy (Feldman, 1973) does not invalidate the theoretical point at stake.
To sum up, allocative justice entails a static view and concerns distribution only, whilst background justice is dynamic and concerns the conditions of both production and distribution in time (Freiman, 2012).
Rawls’s idea of background (procedural) justice does not disregard outcomes in themselves. Even if Rawls’s position is not consequentialist in the strict sense, it is anyway consequence-sensitive (Freeman, 2012). The point is that we have to avoid certain undesirable outcomes, not through ongoing interference and redistribution but through careful formulation of the background rules that govern citizen interactions in time (Pogge, 2007: 179-180). In this regard, we can speak of predistributive egalitarianism (Thomas, 2020). Again, the point is not to defend formal, procedural processes versus substantive outcomes, but to include the latter in the correct way.
As Mandle (2009: 53) aptly writes, summarising Rawls’s central point: “The principles of justice are not designed to determine directly which individuals are entitled to which shares of resources. Rather, they are designed to evaluate the institutional rules within which individuals come to be entitled to particular goods. When the principles refer to ‘inequalities’, these are structural inequalities that may predictably result from the functioning of the various institutional arrangements”.
8
In light of all this, note that the principle often accepted in planning theory and practice, as in many other fields, is not the Rawlsian (non-allocative) principle of difference but what we may call the (non-Rawlsian) allocative principle of difference (Freeman, 2007: 127).
Avoiding Nozick’s challenge: beyond simplistic dichotomies between processes and outcomes
Rawls’s ideas of the basic structure of society and that of background procedural justice are crucial. As regard the former notion, Barry (1995: 214) write: “If Rawls had achieved nothing else, he would be important for having taken seriously the idea that the subject of justice is […] the ‘basic structure of society’”. 9 The thesis that certain basic institutions are the main and primary subject of social justice assessments seems convincing (Frankena, 1962; Barry, 1989; Höffe, 1987; Miller, 2001; James, 2005). Moreover, focusing on background justice (rather than on allocative justice) gives importance to both processes and outcomes in a way that appears appropriate to a constitutional democracy. 10
Combining the ideas of the basic structure and that of background justice enables Rawls
11
– and any approach of a similar kind – to avoid Robert Nozick’s (1974) challenging criticisms of end-state patterned principles of justice
12
(exemplified by the famous Wilt Chamberlain example
13
). Moreover, taking Rawls seriously shows how Nozick’s arguments are not against redistributive approaches in themselves (i.e. against any redistributive approach, as Nozick seems to believe) but only against certain redistributive approaches (e.g. allocative conceptions of justice). As Lovett (2011: 63) notes, the conviction that Nozick’s arguments can be levelled against Rawls is based on a confusion (that also this article underscores): “The confusion lies in assuming that the difference principle is meant to be applied directly to distributions of social and economic goods. This is not the case. The principles of justice, as Rawls stresses many times, are meant to apply to the basic structure of society – that is, to the design of society’s major social institutions and practices”.
In conclusion, Rawls is actually a kind of egalitarian, but not a time-slice egalitarian; the pattern that he intends to weave into society is “a pattern of equal status”, to be applied not so much to a distribution as to “an ongoing relationship” (Schmidtz, 2006: 201; see also Pogge, 1989: 28ff.). 14
An alternative view for planning theory and practice: a multi-strata conception of institutional action and a canvas conception of the just city
To avoid misunderstandings, the fact that the difference principle as it is formulated by Rawls cannot be directly applied to single local policies and plans (according to Rawls himself) obviously does not mean that we cannot develop a post-constitutional approach à la Rawls still paying especial attention to the worst-off (e.g. the least advantaged in a city). Simply put, post-constitutional principles (e.g. principles for local interventions) cannot be identical to the difference principle. In this section, I shall suggest how this could happen. I shall do so not by trying to directly define local substantive principles for the just city, but by identifying the general features they could and should have.
In my view, two main implications of the foregoing discussion for the debate on urban justice are that we need (i) a “multi-strata” view of institutional action; and (ii) a “canvas” conception of the just city.
First, however, a brief clarification is necessary. There are institutions (e.g. public institutions) at different levels, for instance at the national state level and at the local one (e.g. the level of local governments). As we have seen, Rawls uses the expression “basic structure of society” mainly in regard to the former case; but he obviously recognizes – and so does this article – that there are key institutions also at the local level. More than being a mere question of geographical scale, this is a question of administrative “levels” or, better, “stages”, as we will see in what follows. 15
First point: A multi-strata conception of institutional action
Like that of Rawls, many philosophical theories of justice are above all theories regarding the basic structure of society (Barry, 1989; Höffe, 1987). Therefore, their application to single urban policies and plans, at the local level, is neither straightforward nor immediate (Campbell, 2006; Campbell and Marshall, 2006). This is not due to the gap between theory and practice; rather, it is due to the intrinsic nature of many theories of justice. Among the few authors who have clearly recognised this in the planning literature, with specific reference to the Rawlsian perspective, is Klosterman (1978: 45): “Rawls does not suggest that these principles (i.e. the two principles of justice) be used to evaluate specific governmental actions and policies but, rather, limits their use to more fundamental decisions concerning the nature of major social institutions”. Along similar lines, Campbell (2006: 93) writes: Rawls (as well as Habermas) does not intend “his constitutional-level conceptualisations of justice to be applied to the everyday situated judgments with which planning and many other areas of policymaking are concerned”. As regards transportation planning, Nahmias-Biran et al. (2017: 199) observe: “Rawls’s theory of justice deals with the basic structure of society; therefore, it would be a mistake to simply adopt one of Rawls’s principles of justice to the domain of transportation, as has been done in the transportation literature”.
An article in which Howe (1990: 140) discusses ethics in planning contains this comment: “Cleveland’s Rawlsian comprehensive planning effort ultimately failed because as a society we do not accept the difference principle, or the absolute centrality of justice”. In the perspective propounded here, the problems faced in Cleveland were more connected to the questionable attempt to apply a constitutional-level principle to each everyday urban policy.
In their study on elected officials in urban policymaking (which draws on interviews with around 100 elected officials in 12 cities), Schumaker and Kelly (2013: 93) find that “officials have some allegiance to the idea that they should focus on the poor, as suggested by the justice principles of John Rawls, but making a Rawlsian argument is unlikely to be effective because few officials think they should always focus on the poor. Perhaps officials doubt that every policy decision has to improve the conditions of the disadvantaged” (see also Schumaker and Kelly, 2012). Whatever we might think about the motivations generating the answers of the local officials, it is not so strange to find the conviction that we cannot adopt the difference principle for every local public decision; this is simply impossible and far from Rawls’s own view.
Clearly, we can try to imagine how to develop Rawls’s general view more adequately in order to conceive an approach suited to local institutions: that is, a substantive and operative idea of the just city. What this article stresses is that, if we want to follow this line (i.e. build a more convincing Rawlsian approach to urban issues, or any other justice-based approach to this kind of issues), we have to keep in mind that this endeavour will have to fulfil three conditions.
First (let us call this the no-flatness clause), it has to incorporate the idea that this should take place by imagining an appropriate sequence of institutional levels. The institutional environment is not flat; rather, it is organized in layers. Local policies and plans cannot but be understood as developed within – and conditioned by – a broader institutional framework (Wolman and Goldsmith, 1992; Sellers, 2002; McCabe and Feiock, 2005). 16 In particular, when considering issues of justice (in the planning field too: Moroni, 2018 and 2019), a clear distinction between the constitutional and the post-constitutional level of discourse is necessary: that is, a distinction between discourses concerning the basic structure of society and discourses concerning everyday policy decisions. The constitutional level is the level at which we can imagine a group of constitutional delegates conceiving and designing a constitution. Many questions that are crucial for land use issues are constitutional-level questions (e.g. the problem of expropriation for public utility, taking issues, exclusionary zoning: Siegan, 1997; land-value taxation as a pre-distributive mechanism: Kerr, 2016; issues concerning evictions: Strauss and Liebenberg, 2014; the possibility to work on the street: Meneses-Reyes and Caballero-Juárez, 2014; the possibility to build and frequent any type of place of worship: Chiodelli and Moroni, 2017; land grabbing: Montilla Fernández and Schwarze, 2013). The post-constitutional level is the level of the policy activities (e.g. regional and local planning) that occur within the accepted constitutional constraints. These two levels can be understood as analytical levels: that is, as standpoints that anyone can – at any time and even merely hypothetically – assume in order to consider specific issues at the appropriate level and deal with them by acknowledging the argumentative requirements suited to that level. In the case of constitutional democracy, they correspond to real-world situations; that is, to real deliberative stages. At the constitutional level the “veil of ignorance” is thick, while at the post-constitutional level it is partially lifted; partially because some empirical facts are known at the latter level (e.g. the contingent status of a particular metropolitan area), but an impartial view on society (i.e. on individuals comprised in that area) is still required for any public decision. (We can interpret the veil hypothesis as a “thought experiment”, but we can also imagine inserting actual “veil rules” at different decision-making stages; in this case, the “veil approach” becomes an institutional-design strategy that may be implemented, at various institutional levels and through various tactics, in order to impede the adoption of non-impartial views by decision-makers: Vermeule, 2001 and 2007). This theoretical approach has, so to speak, a “stage-wise” structure. In other words, it is an approach that recommends thinking sequentially, from the basic constitutional framework to the development – and subsequent implementation – of increasingly focused laws and policies. Therefore, this view rejects the idea that it is possible to identify a single principle of justice – or a single set of principles – that applies to any level in an undifferentiated manner. Principles suited to the different situations should instead be established step-by-step in an appropriate sequence. Note that this is another way to criticise traditional utilitarianism – that so strongly influenced planning (see e.g. Allison, 1975 and Sillince, 1986). In fact, in the case of utilitarianism, there is only one principle – i.e. the maximisation of collective utility – that is valid for every situation.
Second (no-isomorphism clause), local issues will probably imply something quite different from principles introduced primarily in order to judge the basic structure of society, such as the two Rawlsian principles. This means that principles X employed to design the constitution could imply constitutional principles Y, which in turn imply, at the regional and local level, principles W. To provide an example, in certain countries of the Global South poverty problems are also created by the fact that women do not have the right to own land (Tamale, 2004; Kalabamu, 2006; Mitchell et al., 2008; Linonge-Fontebo, 2018): a principle to design or revise a constitution, focused on creating the best condition for the worst-off, could in this case suggest a constitution granting the right to own land to all, and post-constitutional policies favouring and fostering this right. 17 Another example may be this: certain zoning policies favour the rich and create problems for the poor (e.g. large minimum-lot zoning, that is, a form of zoning reducing housing affordability: Atash, 1990; Trambley, 2020; Karki, 2015): a principle with which to assess a constitution focused on creating the best conditions for the least advantaged could in this case entail, through the various stages, post-constitutional local policies that avoid certain forms of zoning. In other words, intrinsically “redistributive” principles for the design or revision of a constitution do not directly and necessarily imply merely “redistributive” constitutional and post-constitutional strategies. (Clearly, also the reverse might be true: non-intrinsically redistributive principles for the design or revision of a constitution could entail constitutional and post-constitutional redistributive strategies).
Third (no-exhaustiveness clause), although justice makes stringent moral demands upon institutions (including local institutions), this does not mean that there are no other moral demands to which people – as professionals or ordinary citizens, for example – are subject, for instance in urban contexts; simply, the latter are not demands of (social) justice (Porter, 2009). In other words, justice does not cover people’s entire normative world and apply only to specific institutional issues (Galston, 1980: 108; Forst, 2012: 9). Trying to include any moral question into just city issues simply creates theoretical confusion and ineffective local policies and plans. To avoid misunderstandings, a fundamental point should be specified here. Each theory of justice, and a theory of the just city as well, must accommodate different and multiple values (for example, freedom, security, welfare): various substantive theories propound different hierarchical schemes and trade-offs in this regard. The point is that this does not – and could not – cover the entire range of values that may be important for a contemporary urban society. Loyalty towards friends is, for example, one of them. However, the latter do not generally concern a normative theory of institutions, that is, a theory of social justice.
Second point: A canvas conception of the just city
Moreover, I suggest that any kind of theoretical development at any institutional level will have to maintain the idea of background justice. Especially in the case of a constitutional democracy, any theory of justice cannot but be a theory concerning the justness of the (public) framework institutions, both of the major institutions of the basic structure and of the lower-level institutions (down to the local level), once an appropriate sequence is imagined to consider them as well. This implies that a theory of the just city has to fulfil three further conditions.
First (anti-contingency clause), contingent allocative distributions – involving specific individuals with known preferences – are not an issue for the local public institutions once (national and) local background justice has been satisfied; that is, once just (national and) local public institutions have been granted. We cannot look at the concrete allocation of goods or resources in an urban area at a single moment, and in itself, and ask ourselves if it is just or unjust. To provide an example: if a particular business sector in city A, or a particular local industry plant in city B, makes extra profits in a certain period, while respecting all the public rules, this cannot be an issue of justice. And here is another example: if certain specific buildings are vacant in city C at time T (a situation occurring without the breach of any general public rule), this cannot be an issue of justice merely because certain specific individuals in that same city are simultaneously unable to find a house to rent (Moroni et al., 2020; De Franco, 2022). In short, social justice in the city is not an issue concerning particular individuals in specific time slices; rather, it concerns “whatever citizens”, even “potential citizens”, in an ongoing common endeavour. How otherwise could it be possible to take into consideration also the future inhabitants of a city (i.e. future generations)? In conclusion, we need a dynamic approach to the just city and not a static one (based on sections in time). The just city is not the collection of successive desirable “snapshots”; it is instead the desirable “institutional script”.
Second (open-endedness clause), many different physical urban configurations, as well as many different distributions of urban goods and resources, may effectively satisfy a normative idea of (local background) justice; there is no way to judge them and order them from, for instance, the most fair or equitable to the least fair or equitable, once principles of local background justice have been fulfilled. Let us for instance assume that the rules of justice in city D do not impede the distributive patterns X, Y, and Z (nor any of the urban agents’ actions potentially producing them): in this case, no occurrence of one or the other of these situations can be considered unjust. In short, the public rules of justice are the software requiring and granting certain standards, but many unpredictable operations – and combinations of operations, as well as their physical outputs – may be compatible with them.
Third (anti-adhocness clause), local public authorities cannot intervene in an ongoing manner – and independently from local background justice – to obtain particular results. This would make the justness or unjustness of urban situations intrinsically transient, and it would frustrate the expectations and long-term plans of urban agents. In other words, urban agents who have developed legitimate expectations, in compliance with the public framework, at time T1 (e.g. a shopkeeper who has just opened a new business, a developer who has started constructing a building, a house tenant who has entered into a new lease agreement) cannot find these expectations thwarted at time T2 simply because local authorities are reacting in an unpredictable way to contingent urban situations (Brown, 2012: 618). Public institutions – and local institutions also – have to grant a certain degree of general predictability (Moroni, 2007) and avoid generating normative uncertainty (i.e. a situation of unpredictability of upcoming measures). Here the point is rediscovering a model of policy-making based on principles, in place of an extemporary model based on spot-detections and spot-reactions (Landis, 1992; Barnett, 1998; Buitelaar et al., 2021). As Waldron (1989: 88) notes, public action should be guided by accepted, recognizable principles and “not merely by orientation towards certain aims or goals”. The point is that, “to plan our lives, we may need to know, reasonably far in advance, how the state can be relied on to behave in certain circumstances”; however, “such knowledge is in principle unavailable whenever state behavior depends on some official’s discretionary estimation of social costs and benefits at the time” (Waldron, 1989: 88). From this perspective, local authorities should not, for instance, frequently revise local taxes, fees and charges, or negotiate exactions with developers in a discretionary fashion (Selmi, 2011; Hills and Schleicher, 2015), merely to increase local revenues at any occurrence.
In short, we should not expect or require that all cities that satisfy certain background principles of justice exhibit any specific common allocative pattern. Background (local) justice is a sort of “canvas” that cities should share even if local contingent individuals’ and groups’ interactions create different concrete “paintings” over time. In other words, the local canvas should be the common granted justice platform starting from which urban life can variously develop. Without the canvas, “painting” by citizens cannot appropriately start; but, at the same time, it is the “painting” by citizens that create the various concrete cities. A theory of the just city therefore defines the framework and leaves to society – individuals and groups – to work out the details. Consequently, two cities may be equally just whilst the way of life of their citizens may be significantly different. Note that a canvas conception of the just city is perfectly compatible with recognition that a city is a highly complex system characterized by emergence and unpredictability (Moroni and Cozzolino, 2019).
To summarise, the (just) city is a (fair) system of social cooperation over time: countless present and future citizens intentionally and unintentionally cooperate to produce the social-spatial resources on which their claims are advanced. The central question for a (canvas conception of the) just city is therefore the following: How can we improve the chances that unknown urban agents have of successfully pursuing their equally unknown and constantly changing purposes in a complex, open-ended socio-economic environment?
In conclusion, what I call the “canvas conception of the just city” is clearly nothing more than the meta-theoretical skeleton of an approach to the just city, but I hope it may at least suggest – in the limited space of an article – a fresh line of discussion and indications for further research. 18
Conclusion
This article has critically rediscussed John Rawls’s theory of justice from the point of view of planning, in an attempt to contribute to the debate on normative planning theory. After criticising the incorrect way in which the Rawlsian perspective has often been imported into planning theory and practice, it has highlighted two of Rawls’s crucial (meta-theoretical) insights which are instead usually not considered: the idea of the basic structure, and that of background justice. Taking these two ideas seriously suggests that, in planning, we need a multi-strata view of institutional action and a canvas conception of the just city. This implies that any substantive theory of the just city should satisfy at least six (meta-theoretical) requirements: (i) the no-flatness clause, (ii) the no-isomorphism clause, (iii) the no-exhaustiveness clause, (iv) the anti-contingency clause, (v) the open-endedness clause, (vi) the anti-adhocness clause. These six conditions may be interpreted as a reformulation of the classic ideal of the “rule of law” in relation to just city issues.
In light of all of this, an interesting point is the opportunity to shift the planning discourse from the very much debated, but less crucial, distinction between “processes” and “outcomes” to the more important contrast identified here between “background justice” and “allocative justice”, which is the real point in urban matters as well. In short, we cannot but agree that outcomes must be taken into account when pondering on urban justice (this is not yet an issue): but the real questions is what kinds of outcome matter, and how they should be taken into consideration.
