In August 2009 Transparency International Anti-corruption Center (TIAC) applied to Yerevan Municipality to receive access to information on the green spaces in Yerevan city during the period from 1998 to present and took the matter to court when its access to information was denied. Per May 11 2011 court ruling the Administrative Court of Armenia upheld a claim on TIAC Public Organization vs. Yerevan Municipality to requested information and provision of the required documents and bound Yerevan Municipality to provide the necessary information.

According to the claim TIAC requested the following copies of the decisions by the Armenian Government or Yerevan Mayor on the changes of the boundaries of green spaces during the period from 1998 to present; the decisions by the Armenian government and/or Yerevan Mayor on provision of certain parts of the green spaces by ownership or land-use right; architectural plan assignments of the constructions in the green spaces; and the licenses granted for constructions in the green spaces.

On October 27, 2011, the Administrative Court of Appeal of Armenia dismissed Yerevan Municipality's appeal against May 11, 2011 court ruling made by the Administrative Court of Armenia.
