Legal Liability of Principal Employers for Gratuity
Legally, there is nothing to say that the principal employer is liable. Unfortunately, the courts have decided otherwise. There are many cases, including some at the Supreme Court level.
Madras High Court Ruling on Gratuity
This particular case decided by the Madras High Court very clearly states that the principal employer is liable for gratuity to be paid to the contract workers in addition to the liability of the contractor. The judgment is detailed and will take time to read, but it clearly states that gratuity is covered in Section 21(4) of the Contract Labour Act.

I would, of course, be happy if the seniors in the group give their opinion because this matter has come up many times in our audits, and there is a dispute regarding this.
There was also a decision by the Supreme Court in the case of SPIC or one of its fertilizer subsidiaries for contract labor used in Chennai Port, which I cannot find at the moment.
