It's a question borne out of genuine curiosity, please do not derail it with sarcasm or d(***)gree-measuring contests and turn this hopeful into a cynic. Thanks in advance!
All the NLUs other than NLU Tripura have got permanent faculty numbers for law subjects without PhD. It is not yet mandatory for an entry level position even under the UGC norms. Having NET/SET is enough. At NLS, Sudhir has a good practice of giving jobs to young people with good credentials even if they don't have NET clearance yet. They don't get tenure immediately, but all the other benefits are there. That's a good practice to build a good core cohort for the future.
Depends. For private universities including Jindal, yes. For public universities, it may be good enough to land you a Chair Professor position if you have got contacts, a decent CV and play your cards right. A normal professorship you may get, but be prepared to be challenged in a court of law.
All NLUs are primarily UG institutions, hence it is possible to have non-PhD faculty with otherwise decent credentials to do the teaching. NLUs do offer PG and Ph.D. programs as well, but these are secondary (often ridiculed by some viewers in this forum itself). That's what happens. On the other hand, if the institute is a research or a PG institution, then all faculty must have a Ph.D. followed by two to four years of post-doc experience to be Assistant Professors. An example would be IISc.
There are multiple instances of people without PhD teaching the LLM students too across all NLUs. The UGC regulations don't make any distinction between faculty having or not having PhD, other than salary increments. That comes in from your second promotion onward.
For visiting positions, there is no guideline unless the university has one. There are people with only LLB degrees who are in that position in various universities. You need to have a good professional CV.
There's nothing called must. UGC gives guidelines, not regulations. Every university has the right to require a PhD from even an entry level AP, which is why more marks are allotted to that during interviews and it's usually mentioned in the DQ column if not the EQ.
Those who have not qualified NET, PhD degree exempts them from NET.
So every law college in India including all NLUs must accept LLM + NET as basic qualification for Assistant Professor post.
