Can Limitation Act apply to salary arrears for contract employees?

I joined the service as a contract employee in 2017 against a government-sanctioned post and was regularized in 2020. However, a CWP case was filed in 2024 regarding initial contract benefits, promotion, seniority, and other consequential benefits. Can the three-year restriction under the Limitation Act be applied to our case concerning salary arrears? If so, what remedy is available? Additionally, if the restriction is applied, will we at least receive the basic pay of the pay commission as arrears for the contract salary?
