Under the  UT QUOTA proposed  theUTchildren would hold 85% of the total seats for admission in government schools whereas 15 per cent was meant for children outside Chandigarh.
With the new guidelines in place, MBBS candidates who have passed Class X, XI and XII from schools/colleges recognized by the Administration and situated in the UT, as a regular student, will be eligible for MBBS admission. Earlier, students, who had passed Class XII from schools/colleges in the UT were eligible.
MBBS Candidates, whose parents are residents of Chandigarh for the past five years preceding the date of application, even if they do not satisfy the schooling criteria, will also be eligible for MBBS admission.
A residence certificate issued by the office of the Deputy Commissioner will be considered as a proof for the purpose. MBBS Candidates whose parents are employees of Central Government/state government and are on deputation with the UT Administration, including government employees of the UT, employees working in autonomous bodies/companies in which the UT has 20 per cent or more share for the past three years preceding the date of application, even if they do not satisfy the above criteria, will also be eligible for MBBS admission.
The class condition in the new criterion will be implemented in a staggered manner. To begin with, in 2019, the eligibility rule will be limited to Class XII; this will be extended to Class XI in 2020 and, finally, Class X in 2021.
However, MBBS candidates of all three above categories will have to submit an undertaking/affidavit that the candidate has not opted for and claimed the benefit of residence in any other state/UT other than Chandigarh after the declaration of the NEET result, adds Tribune.

As per the rule, 15 % of the total seats of medical course at GMCH-32 are filled from All India Quota, while remaining 85% are filled from those who had passed class-XII from Chandigarh. Chandigarh has its share 77 MBBS seats at the GMCH, of these, 63 are left for the General Category.
The bench also made it clear that the candidates, who have sought the benefit of residence in any other state would be debarred from claiming seats in any other States/ UT, Chandigarh.
Hope this helped.
Best of luck
