No, they don't. They just don't have the power, at least not if you're playing under Rugby Union laws. The referee can decide to consult them and can decide to accept their views, or not, at which point the decision rests with the referee. If you can point me to anything in the laws of the game that says something different, go ahead.Touch judges overturn onfield decisions all the time.
Point being, whatever the touch judge's intervention was today, he didn't "overrule" the ref. The ref may have changed his decision based on a touch judge's report, but that's not the same thing. And if the touch judge intervened without being asked by the referee, he exceeded his authority and the ref should have sent him back to the sideline.
