A federal appeals court struck down a Louisiana law on Monday which prevented Medicaid payments for abortions in case of rape or incest. The court found that the physical and emotional toll of rape and incest can make the abortion medically necessary. T he state had argued that its interest in promoting childbirth allowed it the right to withhold the Medicaid payments, but the federal court disagreed. The court ruled that, because Louisiana receives federal money for its Medicaid program, it must abide by federal mandates concerning the program. Those mandates include funding for abortions in cases of rape and incest.
