Are there any legal implication in early relieving during this COVID 19 lock down period?

Hi, I have resigned in last week of Feb 2020 and at that time at the time of acceptance of resignation, we write that he has to serve notice period as per appointment letter and will get relieve on completing of that, which is last week of May 2020.
Now because of Lock down, there is no such volume of work and even till today he didn't get any single task from our side during this entire lock down and for this there is no deduction in pay for this.
Now we want to relieve him by 17th April 2020, and till 17th April he will get his full salary.
My question is that, are there any legal implication in early relieving during this lock down period?

Hi
Please rephrase the above to make a better understanding of the issue on hand. Is it you who resigned or you are talking on behalf of someone or as a HR you are raising a query?
Legal implication might be difficult as the person here had resigned before the lockdown started and subsequently it [lockdown] was done across the country. There are quite a few areas of defense that the employer may still take if taken to court.
Thanks and Regards
