17. The Centenary Chances were not a matter of right. Neither did any candidate, who had failed to clear all papers within the maximum span period of the course have a right to seek a further chance to clear the papers, nor did the DU have any obligation to provide any such chance. Both Centenary Chances were beneficial dispensations provided by the DU suo motu as it were, as part of its centenary celebrations. They were, therefore, in the nature of a benefice, not a right. The terms on which such a benefit was to be extended to exstudents were also, therefore, a matter entirely within the DU’s province and exclusive discretion. There was no legally enforceable obligation on the DU to provide any Centenary Chance. Having decided, nonetheless, to do so, there was, again, no legal obligation on the DU to provide a second Centenary Chance. Again, having decided to do so, there was no legal obligation on the DU to allow all the papers to be re-attempted in either Centenary Chance. If, therefore, the DU decided to allow all the papers to be re-attempted in the First Centenary Chance, and restricted the Second Centenary Chance to four papers, it was no more than legitimate exercise of the discretion vested in the DU in that regard. There being no right in the petitioner to even insist on any Centenary Chance in the first place, the petitioner can certainly not plead any right to attempt all the backlog papers in either Centenary Chance.
