27 Clause 1.2 is hardly a model of clarity. The first sentence states that the broadcast program allowed by the licence is to be to a standard acceptable to TAB. The second sentence contemplates that both TAB and Tasradio are to decide, not the acceptability of the standard of a broadcast permitted by a licence, but rather the acceptability of the terms upon which the Authority will grant a licence. We would resolve the ambiguity by preferring the view that the parties intended to confer a power of decision upon TAB and that the subject matter of that power was the acceptability of the terms of the licence, including its tenure. The evidence showed clearly that TAB, to the knowledge of the respondents, was vitally concerned with the terms attaching to the transmitter licence, including the period of the licence.[8] Racing broadcasts were vital to TAB's business. The standards laid down by the Authority applied to all broadcasting. TAB displayed no interest in those standards, but was concerned with the particular conditions applicable to the terms upon which it could broadcast programs. We agree with the trial judge that cl 1.2 dealt with the acceptability to TAB of all the terms of the licence offered by the Authority, but further, for the reasons we have stated, TAB was entitled to rely upon that clause and did so. Accordingly, the condition was not satisfied.
