The bishops cited similar laws in other states that were passed, but never went into effect because of legal challenges. In those cases, the laws were found to be unconstitutional, and the state was forced to pay significant sums of money to the lawyers representing the pro-abortion challengers to the laws.

Planned Parenthood, the nation's largest chain of abortion providers, has already said they would file suit against Tennessee if the Human Life Protection Act were to become law.
If Roe v. Wade were to be overturned, it would free up states to enact their own restrictions on abortion.
The bishops said they would prefer to see pro-life legislation less likely to face legal challenges and more likely to be found constitutional. They voiced "urgent support" for an alternative Human Life Protection Act which would, in the event that Roe were overturned, trigger an automatic ban on abortion in the state.
