Rav Moshe absolutely did not defer to him on this. In fact, Tendler disputed Rav Moshe’s decision on brain death and tried to get New York State to legislate against the Orthodox definition of death. When Rav Moshe Sherrer informed Rav Moshe about this, Rav Moshe forced his SIL to retract his letter to the New York State Assemblyman.
