Cairnstores Ltd. Generics (UK) Ltd. & Anor v Aktiebolaget Hassle [2002] EWCA Civ 1504 (22 October 2002)

The Court of Appeal held that the trial judge's interventions during the cross-examination of Dr Rees did not amount to bias or render the trial unfair. The interventions were aimed at clarifying evidence and were appropriate given the context and the witness's expertise. The appeal was dismissed as there was no real danger of injustice or unfairness, and the finding of obviousness and invalidity of the patents stood.
