South Dakota Gov. Dennis Daugaard signed a law March 22 establishing a three-day waiting period for all abortions, a time frame that exceeds other state laws that require 24-hour waiting periods.
The law, effective July 1, also requires women to undergo pre-abortion counselling as a way to make certain that their decision to have an abortion was "voluntary, uncoerced and informed."
Opponents of the new law immediately announced plans to challenge it.
"I think everyone agrees with the goal of reducing abortion by encouraging consideration of other alternatives," the governor said.
