Construction of an ambiguous term against its maker
Therefore, if, on the face of the agreement, there arises any ambiguity or uncertainty as to the construction or interpretation of a clause or a term therein, it must be construed against the maker, namely, the appellants.
Merger of a prior oral agreement in a later written agreement
Even if an oral agreement was made (such as is alleged by the defendant) in July, 1949, it was an agreement in anticipation of the later agreement in writing of the 25th August, 1952. In these circumstances it seems to us that the case falls to be considered in the light of the judgment of Wills J. in the case of Greswolde Williams v. Barneby (17 T.L.R. 110). In that case Wills J. accepted the argument, supported by a volume of authority, that “where an agreement for purchase and sale was followed by a conveyance the terms of the original agreement were merged in those of the conveyance, and could not afterwards be relied upon by either party except for the purpose of interpreting the language of the conveyance, unless there were grounds for rescinding the conveyance because of fraud or for altering it because of mistake.”
