On the principle of construction of a commercial agreement, Scrutton on Charter Parties (17th Edn., Sweet & Maxwell, London, 1964) explained that a commercial agreement has to be construed, according to the sense and meaning as collected in the first place from the terms used and understood in the plain, ordinary and popular sense (see Article 6 at p. 16).
