John T. Mulligan, 73, of Berwyn, a retired lawyer, died of a stroke Friday at Dunwoody Village in Newtown Square.

Mr. Mulligan practiced law for 45 years with the firm of Lord & Mulligan in Media. He was also a solicitor for Marple and Haverford Townships.

As a specialist in real estate and condemnation law, Mr. Mulligan taught courses in the Pennsylvania Bar Association's continuing-education program. In the 1970s and 1980s, many of his clients were business owners whose properties were threatened by the construction of the Mid-County Expressway (Blue Route, I-476). He also represented the owner of a landmark hamburger stand - Charlie's Hamburgers in Springfield, Delaware County - that was demolished when Baltimore Pike was widened.

In 1978, Mr. Mulligan represented a Delaware County woman who had purchased a defective used car. The woman successfully sued the car dealer, and the case was among those used by advocates of a Lemon Law that was passed by the Pennsylvania legislature in 1984.

Mr. Mulligan graduated from St. Thomas More High School in West Philadelphia. He earned a bachelor's degree from St. Joseph's University and a law degree from the University of Pennsylvania.

He served on the boards of St. Joseph University and Overbrook Golf Club.

The son of Irish immigrants, Mr. Mulligan often visited cousins in Ireland. He enjoyed travel, golf, winters in Florida, and summers with his grandchildren at his vacation home in Ocean City.

Since 1959, he had been married to Marie Pinter Mulligan. They met at a church dance.

In addition to his wife, Mr. Mulligan is survived by daughters Mary Shane and Lisa O'Reilly, a sister, a brother, and six grandchildren.

A Funeral Mass will be said at 11 a.m. today at St. John Neumann Roman Catholic Church, 380 Highland Lane, Bryn Mawr. Friends may call from 9 a.m. Burial will be in St. Denis Cemetery, Havertown.
