The U.S. Circuit Court of Appeals in Boston has upheld a lower court ruling favoring deprogrammer Ted Patrick in a suit brought by a Unification Church member involved in an unsuccessful deprogramming attempt.

The appeals court affirmed the rejection by District Judge Francis J. Boyle here last June of a charge by Leslie Weiss, 25, that she had been denied her constitutional rights in an unsuccessful deprogramming attempt on Thanksgiving Day 1974.

In his June ruling, Boyle had said that Weiss had failed to prove her charge that she had been held captive by Patrick and Albert Turner of Warwick, R.I., in whose home the deprogramming attempt took place. He noted that she had testified that she was allowed to roam about the Turner home and that she had decided to pretend she was being deprogrammed to create the impression she was a willing listener.

Weiss had charged that she had been tricked into going to the Turner home by her mother and that she was forced to listen to denunciation of the Rev. Sun Myung Moon's Unification Church for nearly four hours in the Turner basement in an unsuccessful attempt to have her renounce her religious beliefs. She said she finally escaped by jumping from a window the next morning.

Judge Boyle also ruled that Turner and Patrick were motivated "primarily, if not entirely," by "the maternal concerns" of Weiss's mother, who hired Patrick because she feared her daughter's health and well-being were endangered by membership in the Unification Church.

The appeals court said it found no need to go into the constitutional questions raised by Weiss because she "was free to leave."
