Suspension order before inquiry

Dear Sir/Madam, I am 23 from Punjab, India. I am working as a Clerk in an educational institution from 09 Jan 2017 (Contract Basis) contract will expire on 8 Jul 2017. I gave my resignation to Secretary Sir against Principal Madam's behavior with notice period of 1 month on 9 Jun 2017 (with complaints and grievances against Principal). Principal banned me to enter into the institute on 09 June 2017, after that I went there continuously for work, but didn't do any work due to banned entry into institute premises. Secretary Sir gave me a suspension order on 13 June 2017 and inquiry committee is sitting on 28 Jun 2017 regarding complaints levied by me against Principal after suspension. In suspension order they put allegation(false) on me so that I misbehaved with Principal and Teachers, But didn't do anything like this. teachers are with Principal due to afraid off her. Now inquiry committee members are those persons who are very close to Principal and always take side of Principal and with full of bias. Neither Secretary nor Principal is available in committee. Can I appeal for alter of committee members or Secretary Sir and Principal Madam should sit in inquiry or anything unbiased?
