Why is NLU Delhi not a part of CLAT?

There are 27 NLUs in India at present. Some of the top NLUs are- National Law University Delhi (NLU Delhi), NLSIU Bangalore, NALSAR Hyderabad and GNLU Gandhinagar.

NLU Delhi does not consider CLAT results for admissions. It conducts its own All India Law Entrance Test (AILET). 25 NLUs offer admissions based on CLAT results. NLU Meghalaya also does not conduct its admissions based on CLAT. Furthermore, NLU Delhi is not a part of the Consortium of NLUs. 

Dr. Ranbir Singh, the founder of NLU Delhi, gave out a reason in 2012, stating that one of the reasons was that NLU Delhi would be CLAT's 13th Law School. Consequently, it would be the 13th pick when students filled out their choices. There are some financial and administrative concerns as well that have kept NLU Delhi from accepting CLAT results for admissions.
