Конституционный Суд Российской Федерации
The Republic of Tatarstan challenged the amendment in the Constitutional Court of Russia, arguing that the State Duma doesn't have authority over the language policies of the constituent republics. On 16 November 2004, the Constitutional Court declined the appeal. To comply with the court's decision, the decree "On restoring the Tatar alphabet based on Latin glyphs" was officially rescinded on 22 January 2005.
