The binding legal principle is that in interpreting contractual provisions, words must be given their grammatical and ordinary meaning unless this would result in absurdity, repugnancy or inconsistency. Where a contractual clause uses the expression 'and/or', it must be read both disjunctively and conjunctively to give effect to all contemplated scenarios. A qualifier that syntactically follows a phrase applies to all elements of that phrase unless there is clear indication to the contrary. In the context of lease renewal options, where the contract provides for renewal 'on the same and/or new conditions as will be mutually agreed', the requirement for mutual agreement applies to renewal on the same conditions as well as to new conditions. Such an option cannot be exercised unilaterally by the lessee without the mutual agreement of both parties.
