Doing LLB for a Govt. employee

LLB course which is done through distance mode or part-time mode is not recognised by BCI and you can't practice as a lawyer after completing the course.
But there are universities offering LLB course by distance mode and part-time course. The degrees obtained from these institutes are not suitable for practising the law profession. It is useful only for other jobs in the private sector.
There are some private colleges where they don't insist on attendance. But you are a government employee and tomorrow after completing the course a question may come how you have done the full-time course while working in a government organisation and unnecessary complications may arise out of it.
Many government employees will get education leave for improving their qualification. If you have any such chance you try that but don't take any unnecessary risks.

Bar Council of India (BCI) does not recognise any LLB degree obtained in distance mode or by correspondence. So even if someone acquires it then it is only for the academic purposes and not for professional practicing as a lawyer. Some people do it to increase their knowledge in the field of law due to certain career reasons or due to carry out some legal works in private mode.

So there is not a single institute which is recognised or approved by the Bar Council in this regard. If in your case it is intended just for knowledge and skill development in the field of law then there are many institutions which offer it in correspondence mode and some of them are - National Law School of India University Distance Education Department, Bangalore; Guru Nanak Dev University, Amritsar; Banaras Hindu University, Varanasi; Kalinga University, Bhubaneswar etc.

Interestingly, if a person is only interested in learning Law and formal degree is not required then there are some specific coaching or tutorial centres which even provide law education to the interested persons. One can explore that option also.

Three years of LLB by evening classes. No one has said in order to get obtain recognization from the Bar Council of India, the course has to be full time. Previously Delhi university used to run evening classes considering the interest of people towards law.

Eligibility criteria for 3 years LLB via evening classes are the colleges should be approved by the Bar Council of India (BCI). A person must have 50% aggregate marks in any discipline & have a minimum bachelors degree from a recognized university. As per the BCI, the person age limit must be 30 years whereas SC/ST concession of 5 years has been given.
The reason why people prefer evening classes is due to their job & their leaves at the company. They would be having an interest in higher education but couldn't get leaves.

Some of the universities offering 3 year LLB not 5 years LLB

1. National Law Institute University, Bhopal.
2. Law college, Pune.
3. Government Law College, Mumbai.
4. NU JS, Kolkata.
5. KIIT Law School.
6. Amity Law School, Delhi.

But these the BCI wouldn't encourage the part-time or evening classes degree for practising the law. This degree would be added advantage for an individual & can join in a college as a faculty or you can start a tutorial or it may be used for your promotions in a private company.

Bar Council of India does not encourage the distance mode qualification and hence even if you acquire any qualification of LLB by such institutes/ universities, such qualification would prove to be worthless. However, if you are an employee of a Public - undertaking, and have sought permission for acquiring such a qualification, you can go ahead after getting a NOC from your organisation.
Most of organisations have their pulls of staffs with LLB degrees working as Law - officers/ Law - assistant and such a qualification, if they don't possess already will be benifited considerably.
If you are interested for the enhancement of your knowledge in the law - field, you can have such LLB degrees being offered by distance - educations for your own interest.
The few institutes offering such courses are as follows -
1) Amity Law School Delhi.
2) Law College Pune
3) Banaras Hindu University
4) Guru Nanak Dev university etc.

If your aim is to go for a full fledged law practice it can not be done with a correspondence mode degree. On the other hand if it is only to increase the knowledge and skills in this area to help you in discharging your duties effectively then it can be undertaken.

Today a lot of information is available in internet as well as in public libraries and if a person is really interested he can learn the law subject by self study and going through the case histories which are well documented.

I express my gratitude to the learned members for posting their replies to my query. Having said this, I have observed that I would further like to narrow down my query that I want to do the law to become the PCS(J) at the first place and even if it does not happen then I would like to continue the practise only after my retirement. That is why i have been asking that from where i should get LLB degree so that if u want to be the Judge tomorrow, the step should not hinder my progress.
