MADISON, Wis. (AP) _ A federal appeals court has upheld a Wisconsin law that requires women to wait 24 hours before having an abortion.

Thirteen other states have similar laws, including Pennsylvania, where the law was upheld by the U.S. Supreme Court in 1992.

U.S. District Judge Barbara Crabb cited that decision when she ruled most of the Wisconsin law constitutional. Planned Parenthood of Wisconsin appealed the 1997 ruling.

On Thursday, the 7th Circuit U.S. Court of Appeals sided with the state, saying it found nothing impermissible in the stated purposes of the law.

State lawmakers said it was intended to provide women with information about alternatives to abortion and ensure they give voluntary consent for the procedure.

The law, which took effect last year, requires women to meet with a physician at least 24 hours before getting an abortion, except in certain cases of rape and incest.

It also requires doctors to tell patients about the procedure, its risks, alternatives to abortion and fetal development, and to give them state-published information.

Doctors who violate the law could be fined $1,000 to $10,000 and could lose their licenses.

The law provides an exception if a doctor determines that the 24-hour wait could threaten the woman's health. The appeals court said that exception was adequate to protect doctors against the risk of indiscriminate prosecution.

The court also upheld two parts of the law that Crabb rejected _ requiring doctors to inform women about technology that allows them to hear a fetal heartbeat and requiring doctors to tell victims of rape and incest that the father is obligated to pay child support.

Planned Parenthood of Wisconsin spokeswoman Shelly Liebetreu said the waiting period is hard on poor women, particularly those from rural areas, because it requires an additional trip. Only three Wisconsin cities have clinics that perform abortions; all are in the southeast half of the state.

Susan Armacost, a spokeswoman for Wisconsin Right to Life, said the law protects the rights of women.

``Wisconsin's abortion clinics were doing a grave disservice to women when they routinely failed to provide them with crucial information,'' she said.
