As an attorney, Butler became known for his defective drugs
products liability work. In 1971, he won a $2.75 million jury
verdict against
Richardson-Merrell, the company that tested thalidomide, which caused
birth defects. The judgment was later reduced to $500,000. After the first case, Butler went on to serve as plaintiffs' counsel in about 20 more thalidomide cases. Other notable cases in which Butler was counsel including litigation over
Turkish Airlines Flight 981 (which crashed in Paris in 1974) and
Pan Am Flight 73 (which was
hijacked in
Karachi,
Pakistan). Butler was a member of the
Inner Circle of Advocates. Butler was also known for his involvement in the
civil rights movement. As a 35-year-old
city attorney in 1955, Butler became the first vice president of the
Compton NAACP. According to unofficial Compton NAACP historian Maxcy Filer, "The City Council even asked Jim Butler, 'What can we do about this NAACP?' Jim said, 'You accept it .... In fact, here's my membership card.' They all kind of kept quiet for about five minutes." In retaliation for Butler's involvement with the NAACP, the City Council attempted a
recall effort, which narrowly failed. Butler remained involved with the Compton NAACP until 1958, when moved to the
Hancock Park neighborhood, to a home originally built for
Bernard Baruch. Butler lived in the home until he died in 2005. ==Personal life==
