Topeka ? Four bills pushed by abortion opponents received tentative House approval Tuesday, including measures imposing new regulations on clinics and tightening a parental notification law.

One bill, advanced on a voice vote, would require the secretary of health and environment to establish minimum health and staffing standards for abortion clinics.

Another, given tentative approval on a 67-53 vote, amends a 1992 law requiring doctors to notify a parent or guardian when a minor seeks an abortion. The bill specifies that the notice be given in person or by certified mail.

Also advanced, on a 69-52 vote, was a bill making it a crime to injure or kill a fetus, except for an abortion. But abortion opponents see declaring that a fetus is a human worthy of protection as an important statement to make in the criminal code.

The heaviest debate was on a measure allows the state to issue “Choose Life” license plates. It advanced on 66-56 vote.

Final action on all four measures is expected today, when passage would send three of them to the Senate.

In past years, anti-abortion legislators have tried to restrict late-term procedures but found their opportunities limited by the U.S. Supreme Court.

Proposals to restrict abortion have faced strong opposition in the Senate, which is more evenly divided between the two sides.

“I think the agenda for those who support the bills is to damage and pick away at a woman’s right to choose at all,” said Rep. Annie Keuther, D-Topeka, an abortion rights supporter. “It’s just coming from all directions.”
