LOS ANGELES (AP) _ The ailing sister of Chicago sports franchise owner Jerry Reinsdorf filed a $5 million breach-of-contract lawsuit Wednesday against her brother, claiming he cut her off financially.

The Superior Court suit filed by Marvin Mitchelson said the managing partner of the Chicago Bulls and Chicago White Sox gave Judith Reinsdorf $10,000 a month for her care for 16 years.

The 64-year-old Reinsdorf had promised their mother, Marion, that he would always support his sister financially ``to maintain a substantial quality of life according to the family wealth,'' the suit claimed.

Those payments stopped in 1998 because Judith Reinsdorf refused her brother's demand that she stop seeing their elderly mother, the suit said. Marion Reinsdorf died in 1998.

The lawsuit seeks $5 million for past, present and future support based on breach of contract and intentional and negligent infliction of emotional distress.

The nature of Judith Reinsdorf's health problems weren't disclosed. Mitchelson would only say the 59-year-old woman was in poor health. She lives in Los Angeles.

Reinsdorf didn't return a telephone message left at his Chicago office.

Mitchelson pioneered the concept of ``palimony'' when he represented Michelle Triola in a lawsuit against actor Lee Marvin. She sued the actor in the 1976 case which established the right of unmarried partners to sue for property division when they break up.

Triola's right to sue for palimony was upheld but her claim was ultimately rejected, though the actor was ordered to pay her a nominal sum for rehabilitation.
