“83 […] It seems to me that it is at least arguable that the subsections are to be read as follows. Subsection (1) states (to paraphrase) that where there are two subsisting registered trade marks, the use of the latter does not constitute an infringement of the former. Subsection (1B) applies where subsection (1) applies: i.e., where there are two registered marks the second of which is not liable to be declared invalid under sections 47 or 48. Where that is the case subsection (1B) then provides that the later registered mark is not infringed by the use of the earlier mark even though the earlier mark may no longer be invoked against the later trade mark (i.e. may not be deployed as a basis for invalidating the later one). In that case the later registered mark is not infringed by the use of the earlier mark.”
“50. An appellate court will only interfere with a discretionary evaluation where an appellant can identify one or more of the follows errors: (i) a misdirection in law; (ii) some procedural unfairness or irregularity; (iii) that the Judge took into account irrelevant matters; (iv) that the Judge failed to take account of relevant matters; or (v) that the Judge made a decision which was "plainly wrong". 51. Error type (v)… means a decision which has exceeded the generous ambit within which reasonable disagreement is possible. 52. ...The appellate court's role is to police a very wide perimeter and it will be rare that a judge who has exercised a discretion having regard to relevant considerations will have come to a conclusion outside that perimeter... It needs to be underlined that an appellate court in an appeal such as the present is exercising aCPR 52.21 (1) "review" power. It is also well-established that the weight to be given to specific factors is a matter for the trial judge and absent some wholly unjustifiable attribution of weight, an appellate court must defer to the trial judge.”
“at one end of the spectrum, the simple fact of being ‘mucked around’ (Worldwide), to the disruption of and additional pressure on their lawyers in the run-up to trial (Bourke), and the duplication of cost and effort (Hague Plant) at the other. If allowing the amendments would necessitate the adjournment of the trial, that may be an overwhelming reason to refuse the amendments (Swain Mason).”
