"So far as payment of the moneys due to our client, we note your letter indicated the sum of $133,853.33 would be paid on or before 31 January 2007 (this includes the adjustment for the double counting of the invoices 11542 and 11514, which is correct). We note these monies have been paid ." [emphasis added]
48 The plaintiff contends that on the evidence given by Mr Harris called for the defendant, work upon version 6 has been the only work which the defendant has carried out by way of performance of its obligation to enhance the software since 2005, in which time the plaintiff has paid to the defendant some hundreds of thousands of dollars, likely in the order of $800,000. The consequential submission is that the defendant has indeed been paid for the work that it has carried out in developing version 6 and that in terms of clause 24(5), the defendant has been paid for the work which it has written in the performance of that work.
49 Broadly the plaintiff's contention is that standing back from the particular words of the subject agreement, the agreement is seen to have been one whereby the plaintiff came with some software, furnished it to the defendant and did so upon terms that the parties would share the revenue derived from the software from the point where the plaintiff furnished its existing software to the defendant. In return for that share, the agreement provided that the defendant would perform its obligations under the agreement to enhance that software as reasonably required by the customer. Hence the payment which was made was of development fees as defined, as meaning "the fees for software development, support and maintenance, as detailed in this agreement, to be calculated and paid in accordance with this agreement".
50 The contra-submission put by the defendant is that there is no common ground between the parties to the effect that payment has been made to the defendant in respect of development fees qua version 6 as provided for in clause 2. The proposition is that the agreement provided for there to be no payment whatsoever by the plaintiff to the defendant until such time as the software was licensed. The proposition is that through the whole of the development, the defendant was never paid in respect of any work carried out on version 6. The proposition is that upon the proper construction of the agreement, the defendant is not entitled to any such payment up to and until version 6 is licensed out to end users.
51 The defendant's counsel indicated from the Bar table that her instructions were that the moneys acknowledged [in the letter from the defendant's solicitors to the plaintiff's solicitors of 31 January 2007] as having been paid to the defendant, were paid in respect of licence fees concerning versions 3 through to 5, but never with respect to version 6. This is an unsatisfactory manner in which to leave the evidence on an interlocutory hearing and simply means that there is another factual issue for close examination during a final hearing.
Conclusion on serious/prima facie case qua the construction issues
52 There is at least arguably a key difficulty with the defendants suggested construction of the agreement for the simple reason that the agreement expressly deals in terms, with the question of title to the software but nowhere expressly deals with a licence to use the software. One observation with respect to the defendants submissions is that they contend that the above notwithstanding, the agreement is nevertheless to be interpreted as conferring a licence to use as opposed to dealing with title.
53 There are also other areas of some complexity which arise by reference to the need to construe a number of provisions applying the usual principles of construction.
54 Summarising the usual principles the following observations may be made:
