6.  The applicant was born in 1955 and lives in Berlin. 7.  The proceedings at issue in the present application are part of a large number of proceedings which have been brought before the Liechtenstein courts since 2001. All of these proceedings concern, in substance, questions relating to the property rights to considerable assets (more than 14 million Swiss francs (CHF)) which the applicant had brought into five different foundations (including the H. foundation) set up by him in 1999 in Liechtenstein and of which he was the beneficiary. The applicant’s mother G.B., represented by her guardian, and the applicant’s sisters R. and K. claimed in different sets of proceedings that the applicant had not been the owner of the assets he had brought into the foundations, but that these assets had partly belonged to G.B. and partly to their deceased husband and father. 8.  On 30 August 2001 the Regional Court, on a request lodged by the applicant’s sisters R. and K. in interlocutory proceedings, prohibited the H. foundation and the applicant from disposing of assets amounting to more than three million euros (EUR) deposited with the P. bank. 9.  By submissions dated 27 September 2001, received by the Regional Court on 28 September 2001, the applicant’s two sisters brought an action for payment of some EUR 3,3 million against both the H. foundation and the applicant (file no. 2 CG.2001.317). 10.  On 12 November 2003 the Regional Court dismissed the applicant’s request for legal aid as he had not given sufficient information on his financial condition despite the court’s repeated requests. That decision was quashed by the Court of Appeal on 3 March 2004, which found that the Regional Court had been obliged to investigate further into the applicant’s financial condition on its own motion. 11.  On 21 July 2004 the Regional Court, having received further information from the applicant, granted the latter legal aid. 12.  On 28 July 2004 R. and K. withdrew the action against the applicant and maintained it only against the H. foundation. 13.  On 30 December 2004 the Regional Court, having questioned the parties and ten witnesses and having inspected numerous documents, ordered the H. foundation to pay R. and K. some EUR 240,000 each and dismissed the remainder of their claim. It found that the applicant’s allegation that he had received the assets he had brought into the H. foundation as a gift from his mother had not been proven. The applicant had therefore not been authorised to bring the assets of the estate of his deceased father into the H. foundation. The amounts payable to R. and K. corresponded to their respective rights to a share in the deceased’s estate. 14.  On 8 February 2005 both R. and K. and the H. foundation lodged an appeal with the Court of Appeal against the Regional Court’s judgment. 15.  On 7 March 2005 the applicant, being the beneficiary of the H. foundation, requested leave to intervene in the proceedings as a third party and applied for legal aid. 16.  On 14 June 2005 the Regional Court granted the applicant legal aid and appointed him a lawyer. On 26 August 2005 the applicant joined the proceedings as an intervening third party. 17.  On 7 September 2005 the Court of Appeal, granting the H. foundation’s appeal, quashed the Regional Court’s judgment and dismissed the action brought by R. and K. as inadmissible. It found that the plaintiffs, two of several statutory heirs, had not been authorised to claim assets from the H. foundation for their own account. 18.  On 4 May 2006 the Supreme Court quashed the Court of Appeal’s decision and remitted the case to that court. It found that, having regard to the principle of good faith, the plaintiffs had standing to sue the H. foundation as the Court of Appeal had accepted that the applicant had unlawfully brought assets from his deceased father’s estate into the foundation, of which he was the beneficiary. It ordered the Court of Appeal to decide upon the plaintiffs’ and the H. foundation’s appeals in the light of its findings. 19.  Subsequently, the Constitutional Court (file no. StGH 2006/56; decision of 26 March 2007) dismissed the applicant’s constitutional complaint of 26 May 2006 against the Supreme Court’s decision of 4 May 2006. It found that the complaint was inadmissible as the Supreme Court’s impugned decision to remit the case to the lower court did not terminate the proceedings by a final decision on the matter in dispute. 20.  On 21 September 2006 the Court of Appeal, following the remittal of the case to it by the Supreme Court on 4 May 2006, granted the H. foundation’s appeal. It quashed the judgment of the Regional Court dated 30 December 2004, finding that the latter had not sufficiently investigated the facts relevant in order to determine the property of the assets in question, remitted the case to the Regional Court and ordered that court to further investigate the facts of the case. 21.  On 21 November 2007 the Regional Court, granting the applicant’s request, quashed its decision of 14 June 2005 to appoint the applicant a lawyer. The applicant was from then on represented by his wife. 22.  On 10 June 2008 the Regional Court, having examined ten witnesses, essentially by letters of request, and having inspected numerous documents, again ordered the H. foundation to pay R. and K. some EUR 240,000 each (new file no. 02.CG.2006.315-415). The facts it established and the grounds it gave corresponded to those given in its judgment of 30 December 2004. 23.  On 28 June 2008 the applicant and on 9 July 2008 the H. foundation, R. and K. appealed against the Regional Court’s new judgment. 24.  On 25 March 2009 the Court of Appeal, allowing the H. foundation’s and the applicant’s appeal, quashed the Regional Court’s judgment and dismissed the action brought by R. and K. Contrary to the Regional Court and to the courts in parallel sets of proceedings, the Court of Appeal, having taken evidence, found that the assets at issue had belonged to the applicant’s mother alone, and not jointly to her and to the applicant’s deceased father. The applicant had received these assets as a gift from his mother in 1993. R. and K. did not, therefore, have a claim against the applicant as the assets at issue were not part of their deceased father’s estate. 25.  On 1 October 2009 the Supreme Court, allowing the appeal on points of law lodged by R. and K., quashed the judgment of the Court of Appeal dated 25 March 2009 and remitted the case to that court. The Supreme Court considered that the Court of Appeal had not sufficiently established the facts which had led it to the conclusion – which ran counter to the conclusions reached by all other courts before in different sets of proceedings – that there had been a valid contract of donation between the applicant and his mother on the assets in question. 26.  On 19 October 2009 the applicant lodged a constitutional complaint against the Supreme Court’s decision of 1 October 2009 with the Constitutional Court. Relying on Article 6 of the Convention, he claimed, inter alia, that his right to a hearing within a reasonable time had been violated. 27.  On 21 May 2010 the Constitutional Court rejected the applicant’s motion for bias against the judges of the Constitutional Court as abusive. It further dismissed the applicant’s constitutional complaint (file no. StGH 2009/177). 28.  The Constitutional Court found that the complaint was inadmissible as the Supreme Court’s impugned decision of 1 October 2009 to remit the case to the lower court did not terminate the proceedings by a final decision on the matter in dispute. 29.  As to the alleged breach of the right to be heard within a reasonable time, the Constitutional Court found that it could still rule on the alleged human rights violation after the Supreme Court had handed down a final decision. In any event, in cases of excessive delays in proceedings the problem arose that the fundamental rights violation caused thereby could not be effectively redressed. The Constitutional Court could only declare that the length of the proceedings had been unreasonable, but could not undo the delays. It noted in this context that in proceedings before the administrative authorities, a complainant could assume the rejection of the request made by him to that authority when the latter had remained inactive for more than three months and could pursue his case on appeal (see Article 90 § 6a of the National Administrative Justice Act (Gesetz über die allgemeine Landesverwaltungspflege)). However, this did not apply to the proceedings before the Constitutional Court. 30.  As regards costs and expenses, the Constitutional Court ordered the applicant to pay R. and K. lawyer’s costs in the amount of CHF 3,087.05 and declared the court costs uncollectible, referring to its practice in previous proceedings brought by the applicant before it. 31.  It emerged from a letter dated 17 July 2013 from the Court of Appeal to the applicant’s wife that the Court of Appeal had stayed the proceedings before it pending the proceedings before this Court having regard to a proposal made by the applicant to that effect. 32.  By decision of 2 April 2014 the Court of Appeal declared that the proceedings were terminated and that the court costs were to be borne in accordance with the Court Fees Act (Gerichtsgebührengesetz). It noted that by submissions dated 29 January 2014 the applicant, who had revoked his wife’s power of attorney to represent him in the proceedings before that court, the applicant’s sisters R. and K. and the H. foundation had informed the court that they had agreed on a settlement of the case and requested that the proceedings be stayed perpetually (ewiges Ruhen). This Court has not been informed of the content of the settlement. The proceedings were thus stayed ex lege. The Court of Appeal further explained that the proceedings before it had not been continued following the remittal of the case to it by the Supreme Court’s decision dated 1 October 2009 because the applicant had lodged a constitutional complaint against that decision with the Constitutional Court and subsequently an application with the European Court of Human Rights. None of the parties to the proceedings before the Court of Appeal had requested that the proceedings be continued while the complaint and the application were pending before the Constitutional Court and the European Court of Human Rights respectively.
