Law studies and validity

You can manage things like attendance in college, etc., but the law is not in your hands.  We shall respect the law.  You have to obtain permission from your employer to study a law course in evening colleges if they are in your town.

Y ou can pursue a law course as a contractual employee, but you must obtain prior written permission or a No Objection Certificate (NOC) from your employer. This is required for both regulatory and professional reasons. 

The BCI, which governs legal education in India, requires students pursuing an LL.B. to declare their employment status.

For any employment, including contractual, a valid NOC from your employer must be submitted to both your law college and the BCI.

Failure to do so can result in serious penalties, such as your final mark sheet and degree being withheld and your enrolment in any State Bar Council being rejected.

I am not aware of any regulation having the force of law which mandates that a working person requires permission or NOC from the employer to pursue higher studies.
