Original sentence: A major part of the legal battle over banning partial-birth abortion relates to health exceptions, which would permit the procedure in special circumstances.Broadly worded health exceptions in abortion legislation have previously been interpreted by many American courts to include psychological health, which opponents of the procedure contend is so vague that it renders any attempt at prohibiting abortions toothless.Wade, which declared many state-level abortion restrictions unconsitutional, did allow states to impose some restrictions on second- and third-trimester abortions
