DU didn't have records of 4 decades back, then how did they produce Modi's degree?

The Delhi University which produced PM Narendra Modi's degree pertaining to 1978, had replied RTI Activist Anil Galgali in September 2015, that they did not have records of past more that 4 decades, and for obtaining the list of passed out students for the year 1978, Galgali should approach the concerned Degree colleges affiliated to the Delhi University. Anil Galgali has now filed an appeal in the matter. RTI Activist Anil Galgali had filed an query with the Delhi University on 11th September 2015, seeking detailed list of students who has passed out in the year 1978. In a reply the Public Information Officer of Delhi University Mr Jay Chandra informed Galgali that, the Asst Controller of Examinations (Results) & IT Officer (Planning cell) have stated that the query pertains to records almost 4 decades old and hence department does not have the details. According to the Asst Controller of Examinations (Results) the copies of the examination results are sent by the examinations department to the respective colleges, hence for seeking the information the applicant may approach the respective colleges. After the Delhi University made public the degree of the PM Narendra Modi, Galgali has alleged that, it has now become clear that the Delhi University had mislead him in its reply, as the issue of PM Modi's degree too pertained to year 1978 and it has made the details public, means that the Delhi University has in its possession the details of all the students passed out in the year 1978 and hence Galgali has now filed a 1st appeal in the Delhi University seeking the detailed list of all the passed out students of BA of the year 1978. Also in a letter addressed to Vice Chancellor Yogesh Tyagi & Registrar Tarun Raj has expressed surprise over the double standards of the University officials, he further demanded action against the officials who has mislead him by not providing information and also demanded that the University provides him with the detailed list of passed out students in the year 1978.
