In a bill of lading there might be a clause known as general liberty to carry on deck clause which reads“Carrier has liberty to carry GOODs on deck”．This clause frequently gives the carrier the option of stowing the cargo either on or under deck，while also exempting the carrier from all liability for loss of or damage to cargo stowed on deck．

A clause of this type is an option，not a statement．The problem arises when the bill of lading contains this clause，but the face of the bill of lading does not state that the cargo was loaded on deck．Under such circumstances，it would appear that deck carriage is unjustifiable for at least two reasons：a）The general liberty to carry on deck clause is merely an option to carry on deck，a choice which the carrier ordinarily does not make．If the bill of lading does not bear a statement on its face giving notice that the cargo is actually stowed on deck，then by default the option has been exercised in favour of under deck carriage．b）The typewritten or handwritten wording on the face of a bill of lading has precedence over the bill&39;s printed clauses．And a clean bill of lading，because it implies under-deck stowage，is functionally equivalent to a typewritten or handwritten notation on the face of the document calling for carriage below deck．A clean bill of lading therefore overrides the printed liberty to carry on deck clause．

A general deck carriage clause without a statement on the face of the bill of lading that cargo is carried on deck is merely an option not exercised and the deck carriage is therefore a fundamental breach of the contract and the Rules．
