4.  The applicants were born in 1970 and 1935 respectively and live in Sofia and Ruse.
5.  D.D., father of the second applicant and grandfather of the first applicant, and his son P.R., father of the first applicant, owned a plot of land and a house in Popovo.
6.  By two decisions of the mayor of 9 May 1988 and 27 February 1989 the property was expropriated with a view to constructing a residential building. The decisions, based on section 98(1) of the Territorial and Urban Planning Act of 1973 (Закон за териториалното и селищно устройство – hereinafter “the TUPA”), provided that D.D. was to be compensated with a two-room flat in a building which the municipality planned to construct on the expropriated plot, and P.R. with the right to build a house on municipally owned land.
7.  In 1989 the expropriated house was pulled down and in 1994 construction work was started on the site.
8.  By a supplementary decision of 19 April 1991, based on section 100 of the TUPA, the mayor specified the exact location and size of the future flat to be offered to D.D. No supplementary decision was issued however with regard to the right to build a house on municipally owned land which was due to P.R.
9.  D.D. and P.R. passed away in 1998 and 2002 respectively, and D.D.’s wife passed away in 2011. This left the two applicants as heirs of D.D., and the first applicant as sole heir of P.R.
10.  On an unspecified date in 2005 the applicants requested that the mayor of Popovo revoke the expropriation order in respect of their predecessors’ property, under paragraph 9(2) of the transitional provisions of the Territorial Planning Act (Закон за устройство на територията, see paragraph 17 below). The mayor did not respond, which under domestic law was considered a tacit refusal. After the applicants applied for judicial review, the refusal was upheld by the courts, in judgments of the Targovishte Administrative Court (“the Targovishte Court”) and the Supreme Administrative Court of 9 March and 11 July 2006 respectively.
11.  Following a fresh request by the applicants for the revocation of the expropriation order, in judgments of 10 November 2006 and 25 April 2007 the Targovishte Court and the Supreme Administrative Court annulled a new tacit refusal on the part of the mayor, acknowledging that the preconditions for such a revocation had indeed not been met, but instructing the mayor to examine the applicants’ request under paragraph 9(1) of the transitional provisions of the Territorial Planning Act, providing for the possibility of monetary compensation (see paragraph 17 below).
12.  As the mayor failed once again to take a decision on the applicants’ request, on an unspecified date they challenged his new tacit refusal, which was annulled once again by the Targovishte Court and the Supreme Administrative Court, in judgments of 27 September 2007 and 3 April 2008 respectively.
13.  Following that, on two occasions (3 June 2009 and 15 June 2010) the mayor refused expressly to revoke the expropriation order in respect of the applicants’ property. After the applicants challenged these refusals, they were found to be null and void by the courts, the first one in a final judgment of the Supreme Administrative Court of 21 May 2010, and the second one in a judgment of the Varna Administrative Court of 25 March 2011. The courts, finding that the fresh refusals were in contradiction with the earlier court judgments in cases between the same parties, sent the case back to the mayor, instructing him once again to examine it under paragraph 9(1) of the transitional provisions of the Territorial Planning Act.
14.  In April 2011 an expert commission of the municipality assessed the value of the expropriated property and set the amount of compensation to be provided to the applicants at 67,300 Bulgarian levs (BGN). After the applicants challenged that amount, in a judgment of 21 December 2011 the Targovishte Court increased it to BGN 83,500.
15.  That sum was paid to the applicants in June 2012.
