The CAT posted the case for June 7 for hearing the government's view on the matter.
Senkumar moved the CAT challenging the government's decision after senior IPS officer Loknath Behara took charge as state police chief.
In a top level reshuffle in the Kerala Police force on May 31, the new LDF government had shifted Director General of Police Senkumar and appointed Behara in his place.
Senkumar, who is currently on leave, alleged that the government removed him from the post by violating the Kerala Police Act.
"I still have all my vertebras intact. I have never appeased anybody for any posting. I have always tried to be impartial and fair", he had said.
