Job under sports quota awarded due to inter-departmental error — is termination possible?

I was appointed in the Education Department of Himachal Pradesh under the sports quota. The offer was initiated by the Department of Youth Services and Sports, which sent me a letter asking if I was interested in a job matching my qualification. I gave consent, and they forwarded my case to the Education Department. After proper document verification (degree, TET certificate, sports certificate), I received a government appointment letter and joined. I did not apply or request the job—it was offered by the department. Now, another sportsperson (from same sport) has filed a court case saying that the sport I represented is not listed by the Department of Personnel, and is using my appointment as a reference to claim a similar job in the Electricity Department. I have not received any notice or inquiry so far. My question is: Can my appointment be cancelled due to departmental miscommunication? What is the legal protection for someone like me who acted in good faith and was offered the job by the government itself? I seek guidance on whether I should be worried about my job or take any precautionary steps.
