Just one day before a law changing the way such pro-life pregnancy centers in New York City do business would have taken effect, a federal judge has put it on hold.

Judge William Pauley issued an order blocking the city of New York from enforcing its Pregnancy Service Center law while a lawsuit against it goes forward. The law requires pregnancy care centers that do not make abortion referrals or provide artificial birth control to make mandatory disclosures about that to potential clients.

Supporters say they were looking for what they call “truth in advertising” from the centers. Meanwhile, the centers – which would have faced heavy fines and possible closures if the law went into effect – say the law was an attack on their guaranteed right to free speech.

To discuss the judge’s decision, our Matt McClure spoke by phone with Chris Slattery, founder of Expectant Mother Care, and one of the plaintiffs in the lawsuit against the City.
