Though she chooses not to perform the ceremonies, Parker said she passes marriage ceremonies on to other judges so they can be completed.
There’s also this statement that she released to the media back in 2012 (which can be found at the above link):
I faithfully and fully perform all of my duties as the Presiding Judge of the 116th Civil District Court, where it is my honor to serve the citizens of Dallas County and the parties who have matters before the Court.
Performing marriage ceremonies is not a duty that I have as the Presiding Judge of a civil district court. It is a right and privilege invested in me under the Family Code. I choose not to exercise it, as many other Judges do not exercise it. Because it is not part of our duties, some Judges even charge a fee to perform the ceremonies.
I do not, and would never, impede any person’s right to get married. In fact, when people wander into my courtroom, usually while I am presiding over other matters, I direct them to the Judges in the courthouse who do perform marriage ceremonies. If my deputy is not busy, I will even ask him to escort or help these individuals find another Judge who performs the ceremonies. I do this because I believe in the right of people to marry and pursue happiness.
Did anyone else hear Tonya Parker drop a mic? Because I sure as hell did.
