What is the ruling if the pledged item is in the possession of the pledgee, and the pledgee's status changes?

Primary text

If the pledged item is in the possession of the pledgee and his condition regarding trust and safekeeping has not changed, the pledgor or the judge cannot remove it from his possession. However, if the pledgee's status changes in trustworthiness or safekeeping, the pledgor has the right to demand its removal and place it with a trustworthy custodian via the judge.
