‘Whilst the test of substantial relevance applied equally to applications for search warrants made in the context of domestic proceedings and applications made at the request of foreign authorities under the Crime (International Cooperation) Act 2003, its application invariably differed. In context a domestic court asked to assess substantial relevance in respect of foreign proceedings would do so on a necessarily more circumscribed basis than the same court would were the assessment in respect of proceedings before the same court.’
