This is an original proceeding in prohibition. The case arises out of a wrongful death action filed by the survivors of Donald Meiser against Maryland Heights Concrete Contractors, Inc. (hereinafter “Maryland”). Maryland was a subcontractor of *490Meiser’s employer, Charter Development Corporation (hereinafter “Charter”). The plaintiffs alleged that Meiser was killed at a construction site by the explosion of a space heater due to Maryland’s negligence. Maryland denied negligence on its part, asserted contributory negligence by Meiser, and filed a third-party petition against several third-party defendants, including Charter, asserting that each third-party defendant shared responsibility for the death. Charter moved to dismiss the third-party petition against it, asserting that as Meiser’s employer, its liability under The Workmen’s Compensation Law excluded all other liability. See section 287.120, RSMo 1978. After argument on October 20, 1978, respondent Judge Ferriss indicated his intention to sustain Charter’s motion to dismiss. Our preliminary rule in prohibition issued December 18, 1978.
The question is whether Charter, as Meiser’s employer, can be made a defendant in the underlying case under the authority of Missouri Pacific Railroad Company v. Whitehead & Kales Company, 566 S.W.2d 466 (Mo. banc 1978).
We need not examine the breadth and scope of Whitehead & Kales, supra, because the question is answered by section 287.-120.1, RSMo 1978, which provides:
1. Every employer subject to the provisions of this chapter shall be liable, irrespective of negligence, to furnish compensation under the provisions of this chapter for personal injury or death of the employee by accident arising out of and in the course of his employment, and shall be released from all other liability therefor whatsoever, whether to the employee or any other person. . . . ”
The statute, supra, is clear and unambiguous. It operates to release the employer from all other liability. In McDonnell Air. Corp. v. Hartman-Hanks-Walsh P. Co., 323 S.W.2d 788 (Mo.1959), the court allowed the non-employer defendant to maintain an indemnity action against the employer of the injured employee but only on the basis that the employer defendant (Hartman) had breached a duty it expressly agreed (contracted) to perform with the non-employer (McDonnell). The rationale of the McDonnell case, supra, supports the conclusion that, aside from the exception noted therein, the employer is not liable to the non-employer defendant for any sums that non-employer party is liable for to the injured plaintiff-employee in tort.
Other cases cited by relator have been considered. The court holds that section 287.120.1, RSMo 1978, statutorily immunizes Charter, the employer, from common-law liability to Maryland Heights Concrete Contractors, Inc., and Missouri Pacific Railroad Company v. Whitehead & Kales Company, supra, does not remove the immunity conferred by section 287.120.1, supra.
Relator contends section 287.120.1 violates sections 2, 10, and 14 of Art. 1, Mo. Const.,1 and the due process clauses of the U.S. Constitution, amendments 5 and 14. Similar attacks were made upon the Florida statute which immunized the employer from liability in tort for contribution in a suit by a negligent third-party defendant. The contentions were rejected in Seaboard Coast Line R. Co. v. Smith, 359 So.2d 427 (Fla.1978). In speaking about workmen’s compensation, the court stated at 429:
“The Workmen’s Compensation Act, by its express terms, replaces tort liability of *491the employer with strict liability for payment of the statutory benefits without regard to fault. An employer under this Act is not liable in tort to employees by virtue of the express language of the Act. Such immunity is the heart and soul of this legislation which has, over the years been of highly significant social and economic benefit to the working man, the employer and the State. And, whether the injury to the employee is caused by ‘gross negligence’, ‘wanton negligence’, ‘simple negligence’ passive or active, or no negligence at all of the employer, is of no consequence. There is no semblance of suggestion in these statutes that the Legislature intended to make any distinction in degrees of negligence so far as the employer’s immunity is concerned and we see no reason or logic in any distinction. Section 440.11, supra, precludes an employer from being designated a person ‘jointly or severally liable in tort for the same injury to person or property’ as used in the contribution act. This provision seems to be supported by the great weight of authority.”
And thereafter, in addressing the constitutional challenge, the court stated at 429— 430:
“As to the constitutional challenge of Section 440.11, as set forth above, we adopt as ours the views expressed in Coates v. Potomac Electric Power Co., 95 F.Supp. 779 (D.D.C.1951), with reference to the Federal counterpart of our Workmen’s Compensation Act, when the Federal employer immunity was challenged as against the due process clause because the tort liability immunity precluded a third party tortfeasor from obtaining contribution from a negligent employer as follows:
“ ‘[3,4] Enactment of the Longshoremen’s and Harbor Workers’ Compensation Act has been held a valid exercise of the constitutional authority of the Congress .
“ ‘[5] ... by the holding that the Gas Company is lifted from the category of joint tort-feasor by § 905, Potomac Electric is deprived of the right to contribution which it otherwise might have claimed. However, the right to contribution is not a vested right on which legislation may not impinge . . liability in tort is several not joint, however many participate in inflicting the wrong and whether they act separately or in conjunction. Tort-feasors come severally into court, however, many may be brought together, and each is bound to the injured person separately and for the full injury. .. .
“ ‘In a case where the employer has paid compensation under the Act, a balancing of the equities does not require allowance of contribution. The Longshoremen’s Act substitutes for the employer’s common law liability for damages to an injured employee an absolute duty to pay the prescribed compensation, broadening his duty to pay compensation to include injuries for which he otherwise would not be required to respond, . . “To impose a non-contractual duty of contribution on the employer is pro tanto to deprive him of the immunity which the statute grants him in exchange for his absolute, though limited, liability to secure compensation to his employees.” . . . ’”
The holding of Seaboard Coast Line R. Co. v. Smith, supra, is sound and applicable here.
The court holds section 287.120.1, RSMo 1978, is not unconstitutional for any of the reasons asserted by relator in this case.
The respondent trial judge was correct. The third-party petition seeking contribution from the employer Charter should be dismissed. Our preliminary rule in prohibition is quashed.
