In a context where the criminal courts have been drastically affected by coronavirus, this paper seeks to demonstrate that the presumption of innocence risks becoming a further casualty of Covid-19. It will argue that prolonged pre-trial detention of unconvicted defendants has been sanctioned by the senior judiciary under the Custody Time Limit (CTL) Regulations. Following a series of important CTL decisions, a universal position of the senior judiciary, one supportive of government, is emerging: despite the case backlog resulting in defendants facing trial delays of unknown length, the exceptional circumstances of the pandemic which the executive faces, amounts to ‘good cause’ to extend CTLs. It will be argued that the correct approach for courts to follow is that that they must hear evidence that justifies why no court rooms are available before using that to mandate extensions. It will be further contended that these far-reaching decisions came from the senior judiciary's perceived need to mop up the problem posed by widespread refusals to extend CTLs, raising questions as to their ability to act independently of political pressure.
