Administrative Litigation Act Article 237-28

If the High Administrative Court determines that the Urban Plan sought to be declared invalid is unlawful, the Court shall declare the Urban Plan invalid. If the Court determines that matters in the same Urban Plan that are not sought to be declared invalid but are inseparable from the portion sought to be declared invalid, are unlawful, the Court shall simultaneously declare such matters invalid.In the circumstances prescribed in the preceding Paragraph, if the unlawful grounds occur after the Urban Plan has been announced, the Court shall declare that the Urban Plan is invalid starting from the date of occurrence of such unlawful grounds.If the Urban Plan is unlawful and the only legal consequence is to declare such Urban Plan unlawful pursuant to the applicable laws, the Court shall declare the Urban Plan unlawful.The judgment with binding effect rendered pursuant to the three preceding Paragraphs shall have legal effect upon third parties.In the circumstances prescribed in Paragraph 1 of this Article, if the Court determines that another Urban Plan that is inseparable from the portion sought to be declared invalid is also unlawful, the Court may indicate its determination in the reasons of the judgement.
