After a lawsuit from a Christian anti-abortion group, Google is allowing religious organizations to take out ads using the keyword “abortion,” a rare case of the search giant admitting it was wrong.

In March, Google rejected an ad from the Christian Institute, a British organization, that read, in part, “UK abortion law: Key news and views on abortion law from The Christian Institute.”

The group, which wanted to advertise because the House of Commons was considering a bill involving abortion issues, filed a lawsuit against Google in April, saying the company was discriminating on religious grounds.

Google has limits on what can and cannot be advertised; it will not allow ads for products derived from endangered species, for example, nor will it allow ads promoting violence. In the past, Google would not sell the “abortion” keyword to religious groups, but did sell it to other groups, including secular groups, doctors offering abortions and resource sites like Our Bodies, Ourselves.
