An appellate court is set to debate a lawsuit challenging South Carolina’s abortion law about a week after the U.S. Supreme Court considers a similar measure in Mississippi. The 4th U.S. Circuit Court of Appeals has tentatively calendared the South Carolina case for oral arguments the week of Dec. 6, according to an order from the court posted Friday. Planned Parenthood is suing South Carolina to over the measure, which was signed into law by Republican Gov. Henry McMaster earlier this year and requires doctors to perform ultrasounds to check for a so-called “fetal heartbeat.” Opponents have argued many women do not know they are pregnant at six weeks. And, they argue, with such an early deadline, the law gives women little time to consider whether to have an abortion.
