Industrial dispute resolution: Tribunals and conciliation officers have civil court powers to investigate, compel evidence, and enforce awards. Section 49 grants arbitrators, conciliation officers, Tribunals and National Industrial Tribunals procedural autonomy subject to the Code and rules; conciliation officers may enter premises after reasonable notice and enforce attendance, examine witnesses, and compel production or inspection of documents. Conciliation officers, Tribunals and National Industrial Tribunals have the same powers as a civil court for specified matters and their inquiries are judicial proceedings for penal provisions. The provision allows appointment of assessors, deems officials as public servants, vests Tribunals with discretion over costs recoverable as arrears of land revenue, and makes awards executable under Order XXI of the Code of Civil Procedure.
