 In determining the propriety of a particular question posed in the examination for discovery of Dr. Ryan, the test is whether it is reasonable to conclude that the answer to that question might lead Apotex to a train of enquiry that may either advance its case or damage the case of BMS: Apotex v. Canada, 2005 FCA 217 (CanLII), 2005 FCA 217. For example, Apotex is entitled to ask any question that could elicit an admission by BMS as to a relevant fact, or that could elicit information about the existence of documents that have not been disclosed but that meet the test of relevance for the purposes of pre-trial discovery, as set out in the Further and Better Order, subject always to the overriding discretion of a prothonotary or judge to control abuses of the discovery process.
