According to paulgrewal.eth, the voluntary cessation exception in legal contexts, such as cryptocurrency cases, indicates that a defendant’s decision to stop a challenged practice only moots a case if it can be shown that the practice cannot reasonably be expected to recur, as established in Friends of the Earth, Inc. v. Laidlaw Environmental Services (TOC), Inc. This principle can impact ongoing cryptocurrency legal battles by potentially prolonging litigation unless clear evidence of non-recurrence is presented.
