Pillai handed over a letter to Chandy demanding his son's restoration in the cabinet holding that there was no legal hurdle in doing so as no case was now pending against Kumar.
Refusing to make any commitment on the ally's demand, Chandy told reporters that he would respond to the demand on Wednesday.
Pillai, who met reporters after meeting Chandy, said, "Re-induction of Kumar is only a formality as there is no criminal case pending against him."
However, they reached a settlement later and she withdrew the complaints against her estranged husband, setting the ground for a mutually agreed divorce and agreement on partitioning family assets.

Though Pillai now wants son to be taken back to the ministry, political observers feel that it would not be easy as the Congress is stiffly opposed to that.
Recently, Chandy had offered Pillai the chairmanship of the newly formed Forward Communities Commission with cabinet rank.
