John Coffman, an attorney for the eastern Missouri chapter of the American Civil Liberties Union, said the broad definition of coercion also has “strong free speech concerns.” The legislation essentially is intruding into pillow talk and kitchen-table conversations, he said.

“Often things are said in a family in the heat of the moment,” Coffman said. “Those individuals may or may not mean it.”

Supporters said all aspects of the Missouri legislation are intended to ensure women give their informed consent to an abortion — something already required, but with lesser detail, in Missouri law.

In 2006, the Missouri Supreme Court upheld the a 2003 law requiring physicians to wait 24 hours after conferring with women before performing abortions. That law required the consultation to cover such things as “the indicators and contraindicators” and the “physical, psychological and situational” risk factors associated with abortions.

The latest Missouri proposal also “is constitutionally sound,” said Mailee Smith, of the Chicago-based Americans United for Life. She said states have leeway to enact laws to ensure women considering abortions understand the risks.
