Sections 39(1) and (2) of the Act cast on the Board an obhgat10n, according to its powers, to provide all reasonable facilities, if so required by any owner, for various kinds o.f se:vices menti?ned. in clauses (a), ~b) and (d) of section 39(1), which r.1clude services m regard to landmg of goods between vessels and docks in possession of the Board and receiving, storing or delivering goods brought within the Board's premises. The Board under section 39(3) shall, if required, tlllce charge of the goods for the purpose of performing the service. After the goods are thus taken charge of and a receipt given for them, no liability for a>.iy loss or damage which may occur to the goods atl'aches to any person to whom the receipt has been given or to the master or owner of the ship from which the goods have been landed.

It is the Board thus constituted that frames the Scale of Rates and Statement of Conditions under which the services shall or may be performed by it. Every scale and every statement of conditions framed by the Board has to be submitted to the Central Government for sanction under section 44 and it is only when it is so s.anctioned that it has the force of law.
