The decision in this regard was taken at the cabinet meeting chaired by Chief Minister Pinarayi Vijayan here today.
Lakshamana had appealed to the previous Congress-led UDF government in 2015 to compensate him for Rs 33 lakh spent by him to fight the case in which he is an accused.
The bills were examined by the Home Department, which had recommended sanctioning of Rs eight lakh.
After the new government came to power, the matter was brought up before the cabinet once again, following which it was decided not to accept his plea.
