"If Griswold was expressly based on marriage, how could it be cited as a precedent for abortion? One attempt to build a bridge from Griswold to abortion that proved very influential was a law review article advocating legalized abortion published in the fall of 1969 by retired Supreme Court Justice Tom Clark. Clark had been attorney general in the Truman Administration and then served on the Court from 1949 to 1967. He had joined Douglas’s opinion in 1965 to strike down the Connecticut contraception law in Griswold before retiring in 1967. Clark’s article was cited by numerous lawyers and lower court judges. It was quoted to the Justices by Professor Norman Dorsen in January 1971 during his oral argument against the District of Columbia’s abortion law in United State s v. Vuietch. It was quoted by Justice Douglas in his dissent in Vuitch, and by Justice Brennan in his December 30, 1971, letter to Douglas outlining Brennan’s view that the right of privacy included abortion. And Justice Douglas cited the article in his concurring opinion in Doe v. Bolton."
