Hi Sir, I am new to this forum, i have a query regarding the appointment of contact to regular. My Wife is working as a Assistant professor in Punjabi University Patiala in Management Department. She is on contract basis from last more then seven years. She has been recruited via proper interview channel. There is no break in the service in complete tenure. She has done P.H.D with course work. Kindly guide me can she be regularized via legal process? Please share if you anyone has already some court judgement similar to this case which may be helpful. Your help will be appreciable. Thanks in Advance. Thanks, Gagan gaganincontact@gmail.com 9872092110
