Little Rock. Ark. ? Arkansas cannot ban homosexuals from becoming foster parents because there is no link between their sexual orientation and a child’s well-being, the state’s high court ruled Thursday.

The court agreed with a lower court judge that the state’s child welfare board had improperly tried to regulate public morality. The ban also violated the separation of powers doctrine, the justices said.

The board instituted the ban in 1999, saying children should be in traditional two-parent homes because they would be more likely to thrive.

Four residents sued, claiming discrimination and privacy violations against homosexuals who otherwise qualified as foster parents.

The justices agreed Thursday, saying the ban was “an attempt to legislate for the General Assembly with respect to public morality.”

In addition, the court said, the testimony of a Child Welfare Agency Review Board member demonstrated that “the driving force between adoption of the regulations was not to promote the health, safety and welfare of foster children but rather based upon the board’s views of morality and its bias against homosexuals.”
