7th Pay Scale Arrears claim - till date, 7th pay scales are not implemented by my college

Sir, I joined an Unaided Engineering College in Maharashtra on 16-6-1986 as Lecturer. I retired as a Associate Professor in May 2021. Govt. of Maharashtra as per GR dtd 11 Sept 2019, implemented 7 the pay scales to the Engg. College teachers. But till date, 7th pay scales are not implemented by my college.
I want to claim salary difference as per 7th pay scales from 1-1-2016 to 31-5-2021 (retirement date). Can I claim it in High Court or any other lower court?
Please give me a right advice
