"Blackmun’s final opinion left no room for prohibitions on abortion. That was not apparent in the spring of 1972, however. In mid-May, Blackmun wrote “a first and tentative draft” for Roe vs. Wade that stopped well short of declaring a constitutional right to abortion. Instead, it said the Texas law did not give doctors enough guidance. Criminal laws must be clear, the court had emphasized, so people don’t unwittingly commit a crime. Blackmun said Texas physicians could not be sure whether they were committing a crime by performing an abortion on a patient whose troubled pregnancy might risk her life. “I come out on the theory that the Texas statute ... is unconstitutionally vague,” he said in a memo to his colleagues on May 18, 1972. “I think that this [finding] would be all that is necessary for the disposition of the case, and that we need not get into the more complex” issues. In retrospect, this proved to be a crucial time in the court’s handling of the abortion issue. Blackmun had proposed issuing a short opinion that would have struck down the Texas law and the 30 others like it. However, it would have also left the states ample room to revise their laws."
