Dear client,

Your spouse can move proactively in this case to resolve the delay. First and foremost, he ought to correspond with the state-funded college in writing, indicating that he is prepared to begin and asking for the appointment letter before the deadline. He can think about sending a registered letter stressing the recommendation letter's mention of time constraints if there isn't a response or if there is more delay. Your husband may make reference to pertinent Indian legislation if the college doesn't address the problem going forward. You can use the Right to Information (RTI) Act of 2005 to find out why the appointment letter was delayed. Additionally, he might examine the legal options under the Service Law applicable to the educational institutions in West Bengal. For the purpose of guaranteeing on-time appointments, Section 11A of the West Bengal College Service Commission Act, 1979, can be pertinent.

Hope this helps you.
