Objection to Zoning Plan Amendment — Deadlines, Procedure and Judicial Review

Contesting a Zoning Plan Amendment — Time Limits, Procedure, and Judicial Avenues

Zoning plans (imar planları) are the fundamental planning instruments that guide the physical development of cities and determine land-use decisions. Zoning plan amendments regulated under Law No. 3194 on Zoning (İmar Kanunu) may directly affect the property rights of immovable property owners. In this article we comprehensively examine the process for contesting a zoning plan amendment, the applicable time limits, procedures, and judicial avenues.

What Is a Zoning Plan and How Many Types Are There?

A zoning plan (imar planı) is an official plan prepared to guide the future physical development of a settlement, determining land-use decisions and conditions of development. Pursuant to Article 5 of Law No. 3194 on Zoning (İmar Kanunu), zoning plans are divided into two types: the master development plan (nazım imar planı) and the implementation zoning plan (uygulama imar planı).

The master development plan (nazım imar planı) is a plan prepared at a scale of 1:5,000 in accordance with regional or environmental order plans if available, drawn on current maps with cadastral situation superimposed if available, that shows general land-use types, main zone types, future population densities of zones, building density where required, directions and sizes of development of various settlement areas and the principles thereof, transportation systems, and similar matters for the solution of problems, accompanied by a detailed explanatory report, and that serves as the basis for the preparation of implementation zoning plans.

The implementation zoning plan (uygulama imar planı) is a plan at a scale of 1:1,000 that is drawn in accordance with the principles of the master development plan on certified current maps with cadastral situation superimposed, and that shows in detail the building plots of various zones, their density and arrangement, roads, and other information including implementation phases that will form the basis for zoning implementation programmes required for implementation.

The master development plan and the implementation zoning plan complement each other. The implementation zoning plan cannot be contrary to the master development plan. Amending the implementation zoning plan without first amending the master development plan is unlawful. According to Council of State (Danıştay) decisions, the implementation zoning plan must comply with the master development plan.

How Is a Zoning Plan Amendment Made and What Are Its Conditions?

A zoning plan amendment is a revision or change made in accordance with the public interest and planning principles to an existing zoning plan. Pursuant to Article 8 of Law No. 3194 on Zoning (İmar Kanunu), zoning plans enter into force upon approval by the municipal council (belediye meclisi), and plan amendments are subject to the same procedure.

The conditions for a zoning plan amendment are set out in detail in the Regulation on the Preparation of Spatial Plans (Mekansal Planlar Yapım Yönetmeliği). The conditions required for a plan amendment to be made are: the existence of a public interest, compliance with urban planning principles and planning fundamentals, compliance with higher-scale plans, and not disrupting the integrity of the plan. The plan amendment proposal must be submitted together with the plan explanatory report.

An important point to observe in plan amendments is the requirement to set aside an equivalent area. The removal or reduction of social and technical infrastructure areas obtained through a plan is only possible on condition that another area is allocated for the provision of that service. This principle has been reinforced by Council of State decisions and is of great importance for the protection of social amenity areas.

How Does the Posting (Askı) Announcement Process Work and When Does the 30-Day Contestation Period Begin?

The posting announcement (askı ilanı) is the process by which an approved zoning plan or plan amendment is posted in the municipality for 30 days for the purpose of informing the public. Pursuant to Article 8(b) of Law No. 3194 on Zoning (İmar Kanunu), zoning plans approved by the municipal council are posted for 30 days at designated announcement points, and objections may be lodged within this period.

The 30-day posting period begins on the day following the date the plan is posted and ends at the close of working hours on the thirtieth day. This period is not a peremptory limitation period but an administrative objection period. For objections not made within the period, direct recourse to judicial proceedings is available. However, exhausting the objection avenue facilitates the litigation process in practice.

Points to note during the posting announcement process: whether the posting date has been officially announced should be checked. The posting date must be announced on the municipality's website and notice board. During the posting period, plan drawings (pafta) and the plan explanatory report must be made available for inspection at the municipality. It is important that the objection petition passes through the municipality's document registration system and that its date is documented.

How Is an Objection to a Zoning Plan Amendment Made?

An objection to a zoning plan amendment is made by written petition to the mayor's office (belediye başkanlığı) within the 30-day posting period. The objection petition must clearly state the identity information of the person objecting, the block and parcel details of the immovable property, how the plan amendment affects the petitioner's rights, and the grounds for the objection.

The right to object may be exercised by property owners of immovable properties directly affected by the plan amendment, professional chambers (such as the Chamber of Architects — Mimarlar Odası, and the Chamber of City Planners — Şehir Plancıları Odası), neighbourhood heads (muhtarlıklar), and civil society organisations. Pursuant to Article 8(b) of Law No. 3194, objections made during the posting period are examined by the municipal council and decided within 15 days.

The objection petition must address the following points: which property or area is affected by the plan amendment; the designated use of the property in the current plan; how it is changed by the plan amendment; the effect of this change on property rights and the public interest; instances of non-compliance with urban planning principles and planning fundamentals; and any scientific or technical reports available. An objection that is reasoned and based on concrete evidence has a better chance of success.

How Is an Annulment Action Filed Against a Zoning Plan Amendment?

An annulment action against a zoning plan amendment is filed before the administrative court within a 60-day time limit. Pursuant to Article 7 of Law No. 2577 on Administrative Procedure (İdari Yargılama Usulü Kanunu — İYUK), the time limit begins from the date of announcement or notification. The 60-day time limit for filing an action begins upon expiry of the posting period.

The court with jurisdiction over the annulment action is the administrative court. The competent court is the administrative court in the place where the property is situated. The statement of claim must state the identity information of the plaintiff, the name of the respondent administration, the date and number of the plan amendment decision challenged, a summary of the act whose annulment is sought, the grounds of illegality, and the evidence.

Grounds of illegality that may be raised in an annulment action include: defects in competence (the decision being taken by an unauthorised body), defects in form (failure to comply with procedural rules), defects in grounds (absence of reasons justifying the plan amendment), defects in subject matter (unlawfulness of the act), and defects in purpose (pursuing an aim other than the public interest).

In an annulment action, the burden of proof as a rule lies with the plaintiff, although the administration must also demonstrate the lawfulness of the act. Whether the plan amendment is in conformity with urban planning principles, planning fundamentals, and higher-scale plans is established through expert examination. The Council of State emphasises that plan amendments must be based on scientific and technical data.

How Is a Suspension of Execution Order Obtained and What Is Its Significance?

Suspension of execution is an interim measure order that temporarily halts the application of the administrative act until the action is concluded. Pursuant to Article 27 of İYUK, a suspension of execution order is granted when the conditions that (i) execution of the administrative act would give rise to damage that would be difficult or impossible to remedy and (ii) the act is manifestly unlawful are both simultaneously fulfilled.

A suspension of execution order is of great importance in zoning plan amendments. Once a plan amendment is put into effect, construction may begin and situations difficult to reverse may arise. For this reason, it is recommended that a suspension of execution request be made together with the annulment action. The court generally rules on the suspension of execution request after taking the respondent's defence or after the defence period expires.

An appeal against a suspension of execution order may be lodged with the regional administrative court (bölge idare mahkemesi) within 7 days. The appeal does not stay the application of the suspension of execution order. The decision of the regional administrative court on the appeal is final. If a suspension of execution order is issued, the administration must immediately halt implementation of the plan amendment.

How Is an Objection to a Parcelation (Zoning Implementation) Procedure Made?

Parcelation (parselasyon), also called zoning implementation, is a procedure aimed at applying the zoning plan to the land, involving the re-arrangement of parcels. Pursuant to Article 18 of Law No. 3194 on Zoning (İmar Kanunu), municipalities may arrange and divide land and lots within the boundaries of the zoning plan into parcels. In this procedure, a regulation contribution share (düzenleme ortaklık payı — DOP) deduction is made.

In a parcelation procedure, the DOP rate may not exceed 45% (Article 18 of Law No. 3194). The DOP is the proportion cut equally from each parcel to enable the creation of areas allocated for public services within the regulation area. Public service areas such as roads, squares, parks, car parks, children's playgrounds, green spaces, places of worship, and police stations are provided through the DOP.

An objection to the parcelation procedure may be made to the municipality during the posting period, and it is also possible to file an annulment action directly before the administrative court. For the annulment action, the 60-day period begins upon expiry of the posting period of the parcelation procedure. In parcelation cases, the court generally examines compliance with zoning legislation, the correctness of the DOP rate, and the location and value of the assigned parcel.

What Practical Points Should Be Observed When Contesting a Zoning Plan Amendment?

To increase the chances of success in contesting a zoning plan amendment, the posting date must be correctly identified, the objection petition must be prepared with sound reasoning, scientifically and technically supported arguments must be presented, and judicial proceedings must be promptly initiated if necessary.

Practical recommendations: Follow posting announcements regularly. Announcements are published on the municipality's website and notice board. During the posting period, make sure to examine the plan drawings and plan explanatory report. Prepare your objection petition with the support of a city planner or lawyer. Make sure your objection petition passes through the municipality's document registration and retain the registration number.

In the event of rejection of the objection, preparations should be made to file an action immediately. The time limit for the annulment action to be filed before the administrative court must not be missed. A suspension of execution request must necessarily be included in the statement of claim. Since the application of the plan amendment may give rise to damage that would be difficult to remedy, obtaining a suspension of execution order is of critical importance.

In actions filed against zoning plan amendments, according to the settled case law of the Council of State, the following points are examined: whether the plan amendment is in conformity with the public interest, its compliance with urban planning principles and planning fundamentals, its conformity with higher-scale plans, and whether it disrupts plan integrity. The decisions of the Sixth Chamber of the Council of State (Danıştay 6. Dairesi) on this subject are of precedential importance.
