Berlin (UPI) -- Germany's highest court ruled Wednesday that homosexual couples have no legal right to marry, but called on federal lawmakers to consider better legal protection for homosexual couples. The Federal Constitutional Court in Karlsruhe said that refusal of state marriage bureaus to allow homosexual weddings did not infringe against rights of homosexuals because the institution of marriage in Germany, as anchored in the constitution, is only open couples comprised of a man and a woman. "The question does not require any clarification," the Court's ruling said. But the Court, in its brief three-page ruling, also said German lawmakers would have to consider whether the ban on homosexual weddings should be mitigated by new laws which would give same sex couples better legal security. The appeal for homosexual marriages was brought to the Constitutional Court by Cornelia Scheel, daughter of former German president Walter Scheel, and Hella von Sinnen, a TV entertainer, after a marriage bureau refused to wed the lesbian couple. Denmark and Norway are the only countries in Europe which allow homosexual marriages.
