Wrongful dismissal in which court to apply

Hi,

I was a Manager in a Listed NBFC where i was dismissed. But there are some technical flaws that i found out during the dismissal process (during Appeal to the Appellate Authority of our company) which i brought to his notice but he continued with the earlier decision. Now my question is to which court i have file an appeal whether can i file writ petition directly in high court.

Thanks in Advance
