Same-sex marriage activists hopeful amid lawsuit

JUNEAU, Alaska (AP) — Five couples have sued to overturn the nation's first constitutional ban on same-sex marriage.

The couples on Monday sued the state of Alaska, which passed the ban in 1998. The plaintiffs are alleging in federal court that the ban is unconstitutional.

The Human Rights Campaign says there's only three other states — North Dakota, South Dakota and Montana — that don't have legal challenges pending to same-sex marriage bans.
