Doctrine of non-interference or doctrine of judicial stability
Courts of equal and coordinate jurisdiction cannot interfere with each other‘s orders. Thus, the RTC has no power to nullify or enjoin the enforcement of a writ of possession issued by another RTC. The principle also bars a court from reviewing or interfering with the judgment of a co-equal court over which it has no appellate jurisdiction or power of review. This doctrine applies with equal force to administrative bodies. When the law provides for an appeal from the decision of an administrative body to the SC or CA, it means that such body is coequal with the RTC in terms of rand and stature, and logically beyond the control of the latter. Doctrine of primary jurisdiction
Courts will not resolve a controversy involving a question which is within the jurisdiction of an administrative tribunal, especially where the question demands the exercise of sound administrative discretion requiring the special knowledge, experience and services of the administrative tribunal to determine technical and intricate matters of fact. The objective is to guide a court in determining whether it should refrain from exercising its jurisdiction until after an administrative agency has determined some question or some aspect of some question arising in the proceeding before the court (Omictin vs. CA, GR 148004, January 22, 2007). Doctrine of adherence of jurisdiction/continuity of jurisdiction
In view of the principle that once a court has acquired jurisdiction, that jurisdiction continues until the court has done all that it can do in the exercise of that jurisdiction. This principle also means that once jurisdiction has attached, it cannot be ousted by subsequent happenings or events, although of a character which would have prevented jurisdiction from attaching in the first instance. The court, once jurisdiction has been acquired, retains that jurisdiction
