Chief Minister Pinarayi Vijayan signed the necessary files in this regard tonight and the government order would be issued tomorrow, CM's office sources said here.
The apex court had on April 24 directed reinstatement of Senkumar, saying he was transferred by the LDF government "unfairly" and "arbitrarily".
The LDF government had removed Senkumar as the DGP two days after it came to power in May 25 last year.
It ordered notice to Chief Secretary Nalini Netto on the contempt plea and fixed the matter for hearing on May 9.
It also imposed a cost of Rs 25,000 on the Kerala government, which had filed a separate application seeking certain clarifications on its April 24 judgement.
