DEAR ASSUMI,
Court Power:
Court Power is Sphere of Authority or exercising authority, the limits within which any particular Court has authority, right, or authority of a particular court to hear and determine causes, or to execute justice; judicial authority over a cause or class of causes; as, certain suits or actions, or the cognizance of certain crimes, that is within the limits of its authority or commission.
Jurisdiction:
Jurisdiction is the power of a court to hear and decide a case before it. The right and power to interpret and apply the law, and the territory within which power can be exercised. So, Jurisdiction is a term that refers to whether a court has the power to hear a given case. Jurisdiction is important because it limits the power of a court to hear certain cases. If courts did not exercise appropriate jurisdiction, every court could conceivably hear every case brought to them, which would lead to confusing and contradictory results.
The real distinction between Power of the Court and Jurisdiction of the Court is that, Power of Court may be limited but the Jurisdiction of the Court is having more than one sence.
