Objecting to Jurisdiction over the Subject Matter

[1] When it appears from the pleadings or evidence on record that the court has no jurisdiction over the subject matter, the court shall dismiss the same. (Sec. 1, Rule 9). The court may on its own initiative object to an erroneous jurisdiction and may ex mero motu take cognizance of lack of jurisdiction at any point in the case and has a clearly recognized right to determine its own jurisdiction.
[2] Jurisdiction over the subject matter may be raised at any stage of the proceedings, even for the first time on appeal. When the court dismisses the complaint for lack of jurisdiction over the subject matter, it is common reason that the court cannot remand the case to another court with the proper jurisdiction. Its only power is to dismiss and not to make any other order. [3] Under the omnibus motion rule, a motion attacking a pleading like a motion to dismiss shall include all grounds then available and all objections not so included shall be deemed waived. The defense of lack of jurisdiction over the subject matter is however, a defense not barred by the failure to invoke the same in a motion to dismiss already filed. Even if a motion to dismiss was filed and the issue of jurisdiction was not raised therein, a party may, when he files an answer, raise the lack of jurisdiction as an affirmative defense because this defense is not barred under the omnibus motion rule.
