This is an appeal from a summary judgment entered against the plaintiff-appellant, Doyle Parmer, by the Circuit Court of Cape Girardeau County. In June, 1980, the appellant filed a common law tort claim against the defendants-respondents, Frank and Mary Bean, alleging he was injurеd as a result of the respondents’ negligence in modifying a saw used by him in the course of his employment by respondents. As part of their answer the respondents asserted that the tort cause of action was barred by the provisions of the Workmen’s Compensation Law, chap. 287, RSMo (1978).
In February, 1981, respondents filed a motion for summary judgment under Rule 74.04 alleging that the only remedy available to appellant is within the scope of the Workmen’s Compensation Law and that the appellant’s common law tort action is barred. In support of the motion respondents filed an affidavit and exhibits. The appellant filed no memorandum, affidavit or exhibits in opposition to respondents’ motion for summary judgment. The documents on file with the court reveal that the respondents, jointly and individually, operated two businesses. One was а Dairy Queen restaurant, the other a home construction- — carpentry business known as Beacon Builders. Appellant was an employee of Beacon Builders and was injured in the course of his employment. On June 22, 1981, the trial judge granted the motion for summary judgment, and entered judgment against the appellant on the grounds that appellant’s exclusive remedy was under the Workmen’s Compensation Law, pursuant to § 287.120, RSMo (1978).
Section 287.120 provides that the rights and remedies granted the employee under the Workmen’s Compensation Law are exclusive and preclude all common law remedies. Once the employer, the employee and the accident fall under the Workmen’s Compensation Law the case is cognizable by the Workmen’s Compensation Commission and the Commission’s jurisdiction is original and exclusive.
Sheen v. DiBella,
Under § 287.280 RSMo (1978), an employer subject to the provisiоns of the Workmen’s Compensation Law who fails to maintain compensation insurance can be sued at common law by the injured employee. The exhibits filed by the respondents in support of their motion for summary judgment indicate that the insurer acknowledged the existence of a policy covering the Dairy Queen restaurant but denied that said policy covered Beacon Builders. Respondents alleged in their affidavit that Beacon Builders was covered by the insurance policy. Submitted with the affidavit was a copy of the insuranсe policy between the respondents and the insurer. The boilerplate provisions of the policy specifically incorporate the declarations of the parties as part of the policy. On a document denominated “declarations” there is an insurance rate listed for both the Dairy Queen and Beacon Builders. The total deposit premium listed on this document was $594.00. Another document submitted to the trial court was an invoice for *694 the insurance policy in question. This invoice clearly indicates that the resрondents paid a deposit premium of $594.00, and that the charges deducted from that deposit ($534.00) included the premium charge for coverage of Beacon Builders. Based on this evidence the trial court found that there was compensation insurance in effect at the time of the accident which covered Beacon Builders. As a result, the trial judge found that the appellant could not pursue a common law tort claim under § 287.280. Since the Workmen’s Compensation Commission had exclusive jurisdiction under § 287.120, Section 287.280 was not applicable as contended by appellant and the trial court entered a summary judgment against him.
Appellant contends that the respondents failed to meet their burden of proof on the summary judgment. In order to answer appellant’s contention we must first determine whаt the measure of the burden of proof is and whether the respondents have supplied such proof required under the circumstances presented by the case at bar. Our review of the case law reveals considerable confusion and conflict on this question, which stems from the two procedural devices employed to raise the applicability of the Workmen’s Compensation Law as a defense to a common law tort claim. The first device is a motion for summary judgment, Rule 74.04 (1981). The second is a motion to dismiss for lack of subject matter jurisdiction under Rule 55.27 (1981).
A summary judgment is appropriate when the court determines from the pleadings, depositions, and affidavits on file that there is no material issue of fact and that the movants are entitled to judgment as a matter of law.
Gunning v. State Farm Mut. Auto Ins. Co.,
The second procedural method is the filing of a motion to dismiss. A court should grant a motion to dismiss for lack of subject matter jurisdiction whenever “it appears” that the court lacks such jurisdiction. Rule 55.27(g)(3). Once a factual question of the court’s jurisdiction is raised, the movant bears the burden of demonstrating that the court’s exercise of jurisdiction is improper.

Randall v. St. Albans Farms, Inc.,
It is apparent that a motion for summary judgment and a motion to dismiss for lack of subject matter jurisdiction are quite different. Summary judgment purports to be a judgment on the merits with res judicata effects between the parties in which the movant has extremely high burden of proof. A motion to dismiss for lack of subject matter jurisdiction is a preliminary question of the court’s power to act which is not a decision on the merits with res judicata effect, and in which the mov-ant has a lower burden of proof. The next question is which prоcedure is mot appropriate for raising application of Workmen’s Compensation Law as a defense to a common law cause of action. To answer this question we must examine the effect of the remedy created in the Workmen’s Compensation Law.
In
Marie v. Standard Steel Works,
Whether the Workmen’s Compensation Law applies is a question of fact.
Roberts v. Epicure Foods Co.,
It appears that the proper means of raising the Workmen’s Compensation Law as a defense to a common law tort action
primarily
is by motion to dismiss for lack of subject matter jurisdiction. While we believe this is the proper procedural method we recognize Rule 55.27(g)(3) which provides that:
“Whenever
it appears by suggestion of the parties or otherwise that the court lacks jurisdiction of the subject matter, the court shall dismiss the action.” This provision indicates that lack of subject matter jurisdiction can be raised at anytime during the proceedings. The defense cannot be defeated by waiver, acquiesence or even express consent.
State ex rel. Nesbit v. Lasky,
We conclude that regardless of the manner in which the applicability оf the Workmen’s Compensation Law is raised as a defense to a common law cause of action, the trial judge must initially treat it as a motion to dismiss for lack of subject matter jurisdiction. Since this question is a factual one, it is to be left to the sound discretion of the trial judge. The movant will not be required to show by unassailable proof that there is no material issue of fact because the trial judge decides only the preliminary question of his own jurisdiction, which is not a decision on the merits and is without res judicata effect. The movants must prove, as they did in this case, by a preponderance of the evidence that the trial court is without jurisdiction. The provisions of Rule 55.27 and Rule 55.28 establish a flexible and effective procedure for the presentation of affidavits, exhibits and evidence on this factual question оf jurisdiction.
McLeod v. Marion Laboratories, Inc.,
As noted previously, the trial judge could not properly enter a summary judgment in the case at bar. This court has a duty to dispose finally of a case if possible, provided there is a record and evidence upon which we can rule with some degree of confidence in the reasonableness, fairness and accuracy of our final conclusion.
Household Finance Co., Inc. v. Watson,
Finally, appellant alleges that respondents should be estopped from asserting the Workmen’s Compensation Law defense. As noted earlier, application of the Workmen’s Compensation Law goes to subject matter jurisdiction, which cannot be waived. State ex rel. Nesbit v. Lasky, supra. We find that the trial judge cannot, on the basis of estoppel, exercise jurisdiction which is beyond his power. The cause of action before the trial court must be dismissed for lack of subject matter jurisdiction.
Judgment is affirmed and remanded with instructions to enter an order dismissing appellant’s cause of action for lack of subject matter jurisdiction without prejudice.
Notes
. Lack of subject matter jurisdiction can arise in two ways. First, the movant may allege that the pleadings fail to establish jurisdiction as a matter of law. In this situation the facts are stipulated, and the question of jurisdiction is purely one of law. Second, the movant may allege that certain conditions of jurisdiction do not exist, and thus raise a factual issue. In the case at bar the trial court is without jurisdiction if the Workmen’s Compensation Law applies. This question is a factual one.
