The group that helped defeat a measure two years ago to try to outlaw most abortions in South Dakota plans to again open an office in Rapid City to fight a similar ballot measure this year.

The South Dakota Campaign for Healthy Families will open its office at 1315 Haines Ave., Suite C with an open house from 5:30 p.m. to 7 p.m. Tuesday.

"South Dakota's families don't need big Government telling them what they can and can't do," Republican and former State Representative Jan Nicolay, co-chairwoman of the Campaign for Healthy Families, said in a news release. "Families know their own circumstances best, but this ban would strip families of a private, moral decision. And a woman would be forced to carry a pregnancy to term even in the fetus couldn't survive on its own after delivery."

In April, the group VoteYesForLife.com submitted the requisite signatures to put on the ballot a measure that would ban abortion in most cases. Unlike a 2006 law that was overturned by voters, however, the current measure includes exceptions to allow the procedure when necessary to protect the health of a woman and allow abortions in cases of rape or incest.

The 2006 proposal, rejected by 56 percent of voters, would have allowed abortion only to save a woman's life.

As with the 2006 measure, passage would likely lead to a lawsuit that could end up before the U.S. Supreme Court and possibly allow the high court to reconsider its 1973 Roe v. Wade ruling.
