elect recovery under either § 7-433c or chapter 568, the workers’ compensation statutes, when the injury arose out of or in the course of employment.
The purpose of chapter 568 of the General Statutes is to provide compensation for any injury “arising out of and in the course of employment, without regard to fault, by imposing a form of strict liability on the employer.” Jett v. Dunlap, 179 Conn. 215, 217, 425 A.2d 1263 (1979); Klapproth v. Turner, 156 Conn. 276, 279, 240 A.2d 886 (1968). In order to recover under the Workers’ Compensation Act, “[t]he employee has the burden of proving that the injury claimed arose out of the employment and occurred in the course of the employment.” McNamara v. Hamden, 176 Conn. 547, 550, 398 A.2d 1161 (1979).
Section 7-433c, while similar to the workers’ compensation statutes, is a separate and distinct legislation. This statute “ ‘simply [provides] special compensation, or even an outright bonus, to qualifying policemen and firemen,’[and] serves a proper public purpose . . . .” Plainville v. Travelers Indemnity Co., 178 Conn. 664, 668, 425 A.2d 131 (1979). The city contends that the workers’ compensation statutes are the exclusive remedy for injuries arising out of and in the course of employment, even if the injuries claimed are compensable under § 7-433c. We do not agree.
General Statutes § 7-433c, as amended, was enacted in 1971 in response to Ducharme v. Putnam, 161 Conn. 135, 285 A.2d 318 (1971), where this court held that the conclusive presumption prescribed by General Statutes § 7-433a was in contravention of the due process clauses of both the state and federal constitutions.6 Thereafter, the validity of § 7-433c was sustained in

The city claims that the Appellate Session erred by failing to consider the relevance of § 7-433a. The city argues that a void statute cannot operate to repeal a valid statute, and therefore that the 1967 version of § 7-433a *68is relevant. It is axiomatic that a statute declared unconstitutional is unenforceable, but is not repealed or abolished. State v. Menitto, 171 Conn. 141, 147, 368 A.2d 136 (1976).
