The US Supreme Court will hear arguments on what could be a landmark case for discrimination laws regarding same-sex marriage.
It centers around Colorado web designer Lorie Smith who in 2016 refused to create wedding sites for same-sex couples.
She says that her faith would not allow her to create a site for same-sex marriages and after being told she would have to is when she sued the state.
Smith claims the First Amendment allows her to refuse work on religious grounds, while civil rights groups claim she wants a "license to discriminate".
Organizations like the ACLU have made clear for years in cases like these, that if you deny same-sex couples a service it would open the door for more and more denials.
