I spoke to GCR on 22 April [full article behind paywall] about the Administrative Court judgment on the CMA's appeal of a judgment in which a warrant to search domestic premises had been refused. In overturning the CAT's original judgment, the Administrative Court shows that the CMA is not subject (as a general matter) to an additional requirement to show that the individual in question has a propensity to destroy documents.
My reading is that the additional checks and balances required by the European Convention of Human Rights are already sufficiently taken into account by the statutory requirement for a warrant to be issued (cf. inspections of corporate premises which can take place on notice without a warrant under s.27 of the Competition Act 1998). The question of an individual's propensity to destroy evidence might however still be relevant in marginal cases, such as where the individual in question is not centrally connected to the suspected cartel (although is still believed to hold documents).
Leaving aside the legal nuances, this judgment firmly reinstates the position that in an age of home-working, individuals within companies need to be aware of the CMA's powers to carry out unannounced inspections on home turf, as well as in the office.
