HOUSTON (AP) - The Texan whose gay privacy case led to a landmark U.S. Supreme Court ruling that granted privacy rights to gay men and lesbians has died at the age of 68.

John G. Lawrence died in Houston Nov. 20, according to Sarah Wilson of R.S. Farmer Funeral Home in Silsbee, Texas. His partner, Jose Garcia, says Lawrence died of a heart condition.

Mitchell Katine, a Houston attorney who represented Lawrence in the case Lawrence vs. Texas, said he learned of his client's death Saturday while inviting him to an April celebration of the ruling.

Lawrence and Tyrone Garner were arrested in 1998 at Lawrence's home near Houston by sheriff's deputies who found them having sex. The 2003 Supreme Court ruling struck down the Texas state law that made sodomy a crime.
