Oklahoma City (AP) --
The Oklahoma Supreme Court on Monday halted an effort to grant "personhood" rights to human embryos, saying the measure is unconstitutional.
The state's highest court ruled unanimously that a proposed amendment to the Oklahoma Constitution that would define a fertilized human egg as a person violates a 1992 U.S. Supreme Court decision involving a Pennsylvania case and "is clearly unconstitutional." Supporters of the personhood amendment are trying to gather enough signatures to put it before Oklahoma voters on the November ballot.

Opponents contend the measure would ban abortions without exception and interfere with a woman's right to use certain forms of contraception and medical procedures, such as in vitro fertilization.
