Assuming the principals even intend to resume business in its current form.
The Buelher character blames Krell’s prolonged closure on some judicial process and claims the court’s permission is necessary to reopen the doors (and start returning gear to owners).
Usually probate courts aim to maintain the value of assets winding their way through the process. For instance, if the asset were a chicken farm, the court would allow the chickens to be fed, the eggs collected, etc. all actions necessary to maintain the asset value of the business.
But here, we have Krell allegedly being kept under court-ordered closure, allegedly forbidden to get anything into or out of its premises, ensuring its income is reduced to zero and severely jeopardizing its value as an ongoing concern. Makes sense.
