Ronald Reagan Appoints Sandra Day O'Connor as an Associate Justice of the Supreme Court

WASHINGTON, July 7 - President Reagan announced today that he would nominate Sandra Day O'Connor, a 51-year-old judge on the Arizona Court of Appeals, to the United States Supreme Court.

If confirmed, she would become the first woman to serve on the Court.

"She is truly a 'person for all seasons,' '' Mr. Reagan said this morning, ''possessing those unique qualities of temperament, fairness, intellectual capacity and devotion to the public good which have characterized the 101 'brethren' who have preceded her."

President Reagan nominates Arizona appeals court Judge Sandra Day O'Connor to fill the vacancy on the U.S. Supreme Court of retiring Justice Potter Stewart. O'Connor is the first woman ever nominated to the high court.

She will be confirmed by the Senate on Sept. 21 by a 99-0 vote.
