This is a case which I admit worries me a little. The background is that in 1999, the Texas Courts ruled that transsexuals are always to be considered the gender which was listed on their original birth certificate. Kansas referenced this decision from Texas in their own case, In re Estate of Gardiner, 42 P.3d 120 (Kan. 2002), which held the same.
The reason that this concerns me is that I personally get the benefit of being a legally married trans lesbian. If this is reversed, it calls into question the validity of all trans lesbian and trans gay marriages in Texas.
