(RALEIGH) -- An abortion law that was at first vetoed by the Governor then overridden by the General Assembly is being challenged in court by the ACLU, Planned Parenthood and others.   The law requires abortion providers to show an ultrasound to the patient at least four hours before any abortion is performed.

ACLU legal director Katy Parker said lawmakers are intruding where they do not belong.  "We're here today because politicians have once again intruded into the relationship between a woman and her doctor and they've intruded into one of the most personal and private decisions a woman and her family and spouse can make," said Parker.

The bill's primary sponsor is said the lawsuit is unwarranted. Republican State Rep. Ruth Samuelson called it a very defensible bill. "I believe that we're all about making sure women, when they're going to make a very important decision to undergo a surgical procedure, that they have all the information they need to make an informed choice," said Samuelson.

The law is scheduled to take effect later in October, but Parker said they are hoping any injunction will be granted before then so the legal fight can move forward.
