By T.A. BADGER Associated Press Writer ANCHORAGE, Alaska (AP) O The Alaska Supreme Court postponed next week's vote to repeal the city's gay rights ordinance, ruling that the petition that was used to get the measure on the ballot was probably biased in its wording. Supporters of the new ordinance went to court to block the April 20 vote on grounds that state law requires the wording on ballot propositions be impartial. They had lost the first round in Superior Court, but their appeal of that ruling is still pending there. The Supreme Court said Wednesday it was troubled by the referendum's title, ``Referendum Petition to Repeal A `Special Homosexual Ordinance.''' ``While opponents of the ordinance regard it as giving special rights to homosexuals, proponents view it as merely adding sexual orientation to the list of other important personal characteristics ... protected from discrimination in public employment,'' the court said. The Supreme Court said the vote should be postponed until the lower court reconsiders the question of possible bias, because voters would be upset if they voted to throw out the ordinance next week and the vote was later overturned. Chief Justice Daniel Moore dissented, saying the state's impartiality requirement doesn't apply to Anchorage, which has its own procedures for referendums. The ordinance, enacted in January after months of bitter debate, bans discrimination based on sexual orientation for 3,300 city employees and workers hired through municipal contractors. Citizens to Repeal the Homosexual Ordinance collected 20,000 petition signatures, well beyond the 5,700 required. Allison Mendel, lawyer for Alaskans for Civil Rights, said in a television interview ``the court agreed with us that people who signed the petition were swayed and couldn't tell what it was all about. There has been a great deal of confusion.'' Michael Johnston, a leader in the effort to repeal the ordinance, said he thought politics were at work within the court. ``I'm astonished that the court has seen fit to tell the voters of Anchorage that, because the court doesn't like the petition, the voters ought not be able to vote,'' he said.
