Maharashtra NCP chief Bhaskar Jadahv issued a notice to Mete in March this year.
Mete, who belongs to the politically dominant Maratha community, switched his loyalty to the Shiv Sena-BJP led opposition alliance before the Lok Sabha elections.
"I am going to reply to their notice legally. I want to ask NCP that if I was taking forward party's agenda to get reservations for the Maratha community, which was also a part of the party manifesto, then why was I served the notice."
NCP was interested only in Maratha votes, he said.
Mete also criticised NCP's decision to induct Jitendra Awhad -- with whom he is not on good terms -- into the state cabinet.
