Prosecution of higher study to government servant.

I'm working as Assistant Engineer (Ele.) in Karnataka State Govt. on being eligible under rules which provides for Prosecution of Higher Study, I have made my application before the Dept Secretary to grant me permission to Study 3 years Regular LLB Course. but the same request has been rejected stating that the Studying LLB Course is not conducive to the Technical Work which you are doing. Hence, your request has been rejected.
Rule 61 of Karnataka Civil Servants Rules reads as under,
61. (1) (a) The State Government may, with due regard to the
exigencies of public service, depute or grant study leave to a
Government servant for prosecution of a special course of study
consisting of higher studies or specialized training in professional
or technical subjects having a direct and close connection with
the sphere of his duty.
(b) The State Government may also grant study leave to a
Government servant for prosecution of studies which may not be
closely or directly connected with his work but which are capable
of widening his mind in a manner likely to improve his abilities as
a civil servant and to equip him better to collaborate with those
employed in the other branches of public service.
(2) A Government servant who is deputed or granted study
leave for higher studies or specialized training shall not be
entitled to claim any monetary benefit or seniority by virtue of the
higher qualification or training acquired.
(3) The deputation or grant of study leave to a Government
servant for prosecution of higher studies or specialized training
shall be regulate.
Therefore, I would request the Experts to suggest me in this regard.
