DIED. Harold Medina, 102, prominent lawyer, legal scholar and federal judge; in Westwood, N.J. Medina left a lucrative law practice in 1947 to sit on the U.S. District Court for the Southern District of New York. Two years later, he presided over the trial of eleven Communist Party leaders accused of conspiracy to teach and advocate the overthrow of the Federal Government by force and violence. The eleven were convicted after a nine-month trial marked by rowdiness and personal abuse heaped on Medina by defense lawyers. In 1951 Medina succeeded Judge Learned Hand on the U.S. Court of Appeals for the Second Circuit, handing down opinions on a variety of arcane issues. He retired in 1980 after 33 years on the bench.
