[37] The respondents argue that first paragraph under the heading "Variation of our agreement" is a non-promissory declaration, which merely provides information. But that information was given in the preceding, opening paragraph of the General Terms; the first paragraph under the heading "Variations" describes the client being bound by the current General Terms, and implies the solicitors can vary those without reference to the client. The opposite construction would mean either that there could be a very large number of differently worded General Terms, which would be inconsistent with having one current set of General Terms, or else that construction would necessitate the solicitors obtaining approval, from all clients who had entered client agreements on the General Terms, to any proposed variation in the General Terms. That would be most unwieldy and difficult, and not what the solicitors intended. The whole point of General Terms is that those apply generally to all clients. The submission by Mr Davis accords with the contents of the Engagement Letter, which enclose the current General Terms, and advises that those are amended from time to time. There is no suggestion that the apparently regular amendments will require the client's agreement, or any client's agreement. Those General Terms and that Engagement Letter are therefore inconsistent with clause 20 of the notice in the schedule. That is because the contents of the General Terms assert that those, and the Engagement Letter, are "our agreement". So when the General Terms are varied, the terms of the agreement are varied. On this point I respectfully disagree with McMurdo J.
