A Christian web designer has a First Amendment right to refuse to create websites for same-sex weddings, the Supreme Court ruled Friday in a decision that dilutes legal protections for LGBTQ people.

By a 6-3 vote, the justices sided with Lorie Smith, an evangelical Christian and Colorado web designer who opposes same-sex marriage. Colorado law bars businesses from discriminating on the basis of sexual orientation, but Smith argued that the free speech guarantee of the federal Constitution entitles her to an exemption from that law.

The high court’s conservatives agreed. They ruled that Smith has a right to offer design services for opposite-sex weddings while refusing those services for same-sex weddings.
