Please advise can i approach to labor court for justice.

Dear Amit
Only a "workman" under ID Act can create an Industrial Dispute. However if your job profile does not dominantly consist managerial and administrative jobs you may make efforts to raise a dispute under section 2A of ID act approaching conciliation officer (Asst commissioner of Labour) of your region. The matter can be admitted to the industrial tribunal/labour court only upon going through the process called conciliation.

If the said employee is considered a non-workman, he has to approach for remedy to a civil court under Sec.9 of CPC or Order 37 of CPC. But, I could hardly find any verdict of any court including the honourable Supreme court in support of this. Can any one supply a case law in support of this?
