Landlord and tenant – Lease. The lease entered into by the defendant European Medicines Agency (the EMA) with the claimants would not be frustrated on the UK's withdrawal from the EU, as it was neither a case of frustration by supervening illegality nor one of frustration of common purpose. The Chancery Division further rejected the EMA's arguments that it would not have legal capacity to act in relation to the lease and that a self-standing rule of EU law served to absolve it of its obligations post-Brexit.
