Tauziat, a former US Open finalist, courted controversy by testifying in favour of De Camaret in a court case which ended with the former coach being jailed for eight years.
De Camaret was found guilty of raping two female tennis players, aged 12 and 13 at the time.
FFT director general Gilbert Ysern branded Tauziat's testimony "deeply disturbing" and said he would be asking her to resign from her position on the organisation's committee.
But Tauziat is standing firm and said she has no intention of stepping down.
“I have two months in office,” Tauziat told French newspaper Sud Ouest. “I have no reason to do so. I did not know that testifying in court was a crime.
“I am very responsible. I am the fuse in the case. There were 20 witnesses at the trial in his favour. They have not been publicised. If Regis is guilty, he must pay. But no one should give me lessons.”
