A person held in custody cannot leave the institution. But what happens when staffing shortages also restrict the freedom they retain inside it?
The Supreme Court of Canada is scheduled to hear that question on October 13 in Diggs v. Nova Scotia. The appeal concerns rotational lockdowns at the Central Nova Scotia Correctional Facility and whether restrictions arising from operational decisions can be challenged through habeas corpus. No Supreme Court judgment has been released.
The case could clarify the route available to people seeking judicial review of significant restrictions during detention.
How the dispute reached the Supreme Court
Durrell Diggs and Ryan Taylor Wilband were held on remand when staffing shortages resulted in rotational lockdowns. They brought habeas corpus applications alleging an unlawful deprivation of their residual liberty.
The application judge declared the lockdowns unlawful. The Nova Scotia Court of Appeal allowed the government’s appeals and set those declarations aside. The Supreme Court is now considering the availability of habeas corpus for this kind of restriction.
That procedural history matters. The appeal should not be presented as a Supreme Court finding that staffing-related lockdowns are lawful - or unlawful.
The issue is access to review as well as institutional operations
The phrase “residual liberty” directs attention to freedom retained within custody. The challenge concerns additional restrictions imposed on people already detained, rather than simply whether their original detention was authorized.
The operational context makes the case particularly consequential. Institutions must manage staffing and security, while people in custody experience the consequences of those decisions directly.
The legal question is how those competing considerations should be examined and through which procedure.
For counsel, access to an effective review process can be as important as the eventual merits. A restriction may change before a lengthy proceeding concludes. That makes timing, evidence and the identification of the challenged decision central to litigation strategy.
What lawyers should watch
The eventual reasons will need to be read carefully for their scope.
A ruling about the availability of habeas corpus would not necessarily resolve every challenge to prison conditions. Nor would recognizing a review route automatically establish that a particular restriction was unlawful.
Practitioners should watch for how the Court addresses the nature of the alleged deprivation, the significance of an operational explanation and the distinction between an individual restriction and an institution-wide policy.
Those questions could affect how future applications are framed.
Building the factual record
As a practical matter, counsel assessing a lockdown challenge should establish precisely what changed: the restrictions imposed, their duration, their effect and the institution’s explanation.
A general statement that conditions became worse may not communicate the same legal issue as a documented account of a specific additional deprivation.
The record should also distinguish what the institution decided from what happened in practice. Rotational arrangements can affect different people differently, making chronology and individual circumstances important.
For now, Diggs is a pending appeal about the reach of a review mechanism.
The question is not only what freedom remains in custody, but how a person can ask a court to protect it.
