Section 58(2) in The Naval Ceremonial, Conditions Of Service And Miscellaneous Regulations, 1964
(2)The flags of other functionaries ordered to be hoisted in ships of war in accordance with Regulations 60 to 62 shall not displace at the mast-head the flag of an Admiral of any grade nor the broad pendant of a Commodore.
