5.  The applicants were born in 1972, 1980, 1937 and 1925 respectively and live in Vilnius.
6.  On 5 November 1991 L.N. (who later died – the first and the second applicants became her heirs), the third and the fourth applicants asked the Lithuanian authorities to restore their property rights in natura to a house in Kaunas, nationalised in 1940s.
7.  In September 1993 L.N., the third and the fourth applicants were asked by the authorities to provide some additional documents necessary to proceed with the restoration of their property rights. L.N. submitted the necessary documents to the Kaunas City Municipality.
8.  In March 1995 L.N. and the fourth applicant agreed that the property rights to one room of the house would be restored to their brother – the third applicant. On 30 March 1995 the third applicant wrote a letter to the authorities, asking them to restore the property rights to 22.4 sq. m of the house and one room of 10.32 sq. m. He also asked to decide the question of the restoration of property rights to a remaining part of the house at a later stage.
9.  By a decision of 11 April 1995, the Kaunas City Council restored L.N.’s, the third and the fourth applicants’ property rights to a house in Kaunas in equal parts. The Kaunas City Council held that 22.42 sq. m of the house would be returned to L.N., the third and the fourth applicant in natura in equal parts and that a room of 10.32 sq. m would be returned in natura to the third applicant. The decision also indicated that the remaining part of the house would be returned in natura when the tenants of the house had been provided with other premises, or compensation would be paid if the premises were not returned.
10.  In July 1995 L.N. and the fourth applicant asked the authorities to pay them compensation for the part of the house that had not been returned in natura.
11.  In March 1996 L.N., the third and the fourth applicants wrote a letter to the authorities, stating that they refused the property that had already been returned to them in natura, and asked to be paid compensation for the entire house.
12.  In September 1996 the third applicant, who by an agreement approved by the notary in 1995, was representing L.N. and the fourth applicant, withdrew the application of March 1996 (see paragraph 11 above) and confirmed that 22.42 sq. m of the house and 10.32 sq. m had been returned to L.N., the third and the fourth applicant in natura.
13.  On 23 September 1996 L.N., the third and the fourth applicants asked the authorities to pay them compensation for the part of the house that had not been returned to them in natura and stated that they agreed to partial compensation until the full market-value compensation figure had been calculated.
14.  Following the request of L.N., the third and the fourth applicants (see paragraph 13 above), the Kaunas City Municipality assessed the value of the entire house and on 8 October 1996 set it at 239,190 Lithuanian litai (LTL – approximately 69,274 euros (EUR)) in total, the third applicant signed for himself and as L.N.’s and the fourth applicant’s representative, signalling their agreement to such compensation. On the same day, the Kaunas City Board amended the decision of 11 April 1995, establishing that the remaining part of the house would not be returned, compensation of LTL 79,730 (approximately EUR 23,091) would be paid to L.N., the third and the fourth applicants each, and that the remaining part of the compensation would be paid when the market value of the house had been calculated. Following this decision, L.N., the third and the fourth applicants were paid compensation on 17 October 1996 and 18 October 1996.
15.  On an unspecified date L.N., the third and the fourth applicants lodged a claim with the domestic courts in order to have the part of the decision of the authorities of 11 April 1995 by which the premises of 22.42 sq. m of the house had been returned to them in natura annulled.
16.  On 24 October 2000 the Kaunas Regional Administrative Court decided to annul the part of the decision of 11 April 1995 by which 22.42 sq. m of the house had been returned in natura and to oblige the Kaunas City Board to pay monetary compensation for this property.
17.  Accordingly, on 18 September 2001 the decision of the authorities of 11 April 1995 was amended and it was decided to pay monetary compensation for the 22.42 sq. m of the house.
18.  The value of the property was calculated on 14 April 2008. On 1 June 2009, in accordance with an application by L.N., the third and the fourth applicants to receive compensation for 22.42 sq. m of the house, LTL 30,000 (approximately EUR 8,689) in total were paid to them.
19. In November 2006 the Kaunas City Municipality Administration asked the Centre of Registers to assess the value of the house and to establish the difference between the value assessed and the compensation that had already been paid. In January 2008 the Centre of Registers assessed the market value of the house in 1996 at LTL 855,000 (approximately EUR 247,625) and established that the remaining compensation to be paid was LTL 615,809 (approximately EUR 178,350) in total.
20.  On 19 March 2008 the authorities amended the decision of 11 April 1995 and established that L.N., the third and the fourth applicants had to be paid compensation amounting to LTL 615,809 (approximately EUR 178,350) in total.
21.  On 26 March 2008 L.N., the third and the fourth applicants were asked to fill in a form in order to receive their compensation; they did so on 1, 20 and 4 April 2008 respectively. The compensation was adjusted in line with the inflation index and amounted to LTL 818,458 (approximately EUR 237,042) and was paid on 17 July 2008. Each person received LTL 272,819 (approximately EUR 79,014).
22.  On an unspecified date L.N. died, and the first, the second applicants, who became her heirs, the third and the fourth applicants lodged a claim with the Kaunas Regional Administrative Court, asking for the annulation of one part of the order of the authorities of 19 March 2008 (see paragraph 20 above), and to oblige the authorities to calculate the remaining compensation as well as the compensation that had already been paid in accordance with the market price of the house in 2008. They also asked to be awarded damages.
23.  On 9 March 2009 the Kaunas Regional Administrative Court decided to annul one part of the decision of the authorities of 19 March 2008 and to oblige the authorities to recalculate the compensation for the remaining part of the house in accordance with the market value in 2008. The court decided to reject the claim for damages as no unlawful acts by the authorities had taken place.
24.  The applicants appealed, and on 29 March 2010 the Supreme Administrative Court partly overturned the decision of the court of first instance. It referred to a similar case of the same court where it had held that the value of the property had had to be assessed in the light of values when the decision to restore property rights had been taken, and that the assessment of the value at a later stage might have created grounds for unjust enrichment. The Supreme Administrative Court also referred to the same case where it had held that although the authorities had not taken the necessary actions to calculate the remaining part of the compensation from 22 October 1996 until 28 April 2008, these had not been appropriate grounds for annulling the decision of the authorities to pay the remaining part of the compensation. The remaining part of the decision of the court of first instance was left unchanged.
