A near­ly 10-year bat­tle for gay rights in Trinidad and To­ba­go could end on Wednes­day at a fi­nal ap­peals court in Eng­land.

Supreme Court judges in Lon­don held a hear­ing on a land­mark hu­man rights case that could de­crim­i­nal­ize gay sex in the east­ern Caribbean na­tion, po­ten­tial­ly set­ting a prece­dent for the large­ly con­ser­v­a­tive Caribbean re­gion.

The case was filed in Feb­ru­ary 2017 by Ja­son Jones, who ar­gues that so-called “bug­gery” laws in the twin-is­land na­tion that pro­hib­it gay sex, dat­ing from when the coun­try was a British colony, are un­con­sti­tu­tion­al. Those found guilty could re­ceive up to five years in prison.
