7.  The applicant is a limited partnership company founded in 1986 and based in Helsinki. 8.  The applicant company, which was running a restaurant in Helsinki, rented the restaurant premises from an insurance company, Keskinäinen Henkivakuutusyhtiö Suomi (KHS). In 1994 it was offered the opportunity to rent more premises, which would be renovated to be suitable for restaurant use. When the renovation was finished, the applicant company found that there were excessive toilet facilities and that part of the planned restaurant facilities were missing, especially those planned to be built in the cellar. The applicant company paid 251,000 Finnish marks (approximately 42,200 euros) for the renovation expenses and the monthly rent was raised considerably. The amended rent contract had been signed before the extension work commenced. 9.  In 1997 the applicant company instituted civil proceedings against KHS before a Division of the Helsinki District Court (käräjäoikeus, tingsrätt) known as “the Housing Court” (asunto-oikeus, bostadsdomstolen). The applicant company claimed that there had been a breach of the rent contract, as the newly renovated facilities did not correspond to the original plan, on the basis of which the applicant company had signed the amended rent contract. KHS disagreed with the applicant company, arguing that even though there had originally been a plan to build restaurant facilities in the cellar, it had later proved to be impossible to build such an extension and that the applicant company had been aware of this before signing the contract (see paragraph 19 below). 10.  On 17 September 1997 the Housing Court found in favour of the insurance company, rejecting the applicant company's action for compensation in accordance with the Act on Commercial Leases. 11.  The applicant company appealed to the Helsinki Court of Appeal (hovioikeus hovrätt), requesting that the District Court's decision be quashed. On 11 December 1997 the Housing Court Division of the Court of Appeal upheld the District Court's decision without an oral hearing. One of the members of the Court of Appeal, M.P., was a member of the Finnish parliament at the time. He had been an expert member of the Court of Appeal since 1974. From 1987 to 1990 and from 1995 to 1998 he was also a member of parliament. For the latter period the date of election was 19 March 1995. 12.  On 9 February 1998 the applicant company applied to the Supreme Court (korkein oikeus, högsta domstolen) for leave to appeal, complaining, inter alia, about the lack of independence of Judge M.P., who had both legislative functions as a member of parliament and judicial functions as a member of the Court of Appeal. On 5 May 1998 the Supreme Court refused the applicant company leave to appeal.
