completely, and without any denial; promptly, and without delay, conformably to the laws.
The purpose of part I, article 14 was to make civil remedies readily available, and to guard against arbitrary and discriminatory infringements on access to the courts. State v. Basinow, 117 N.H. 176, 371 A.2d 458 (1977); 8 Bravenic, The New Hampsh ire Bill of Rights in the Constitution of 1784 and the Treatment of Dissenters During the American Revolution, 8 N.H.B.J. 244, 248 (1966).
This court has held that the rights guaranteed by part I, article 14 “are necessarily relative.” Sousa v. State, 115 N.H. 340, 343, 341 A.2d 282, 284 (1975); Opinion of the Justices, 113 N.H. 205, 209, 304 A.2d 881, 885 (1973). The article does not prohibit all impairments of the right of access to the courts. Compare State v. Cushing, 119 N.H. 147, 399 A.2d 297 (1979) with State v. Basinow supra.
Part I, article 14 does not guarantee that all injured persons will receive full compensation for their injuries. Cf.Hackett v. Perron, 119 N.H. 419, 422, 402 A.2d 193, 195 (1979). Where there exist compelling public policy reasons, a person injured by the negligence of another is in some instances barred from recovery altogether. See, e.g., RSA 508:12 (Supp. 1977). Similarly, the legislature has established limits on the amount of recovery in various actions, including medical malpractice, RSA 507-C (Supp. 1977), and wrongful death, RSA 556:13. We are not prepared to hold that all such limitations on the amount of recovery violate the constitutional rights of New Hampshire citizens. See Sousa v. State supra; cf. Duke Power Co. v. Carolina Environmental Study Group, 438 U.S. 59 (1978) (nuclear power plant accidents, U.S. CONST, amend. V); New York Central R.R. v. White, 243 U.S. 188, 201 (1917) (workmen’s compensation).
The plaintiffs’ second argument is that RSA 507-B:4 (Supp. 1977) denies them equal protection of the laws, in that it improperly creates different opportunities for recovery for victims of torts of the specified governmental units than for victims of private tortfeasors. The equal protection clause mandates that “those who are similarly situated be similarly treated.” Belkner v. Preston, 115 N.H. 15, 17, 332 A.2d 168, 170 (1975); U.S. CONST, amend. XIV; N.H. CONST, pt. I, art. 1.
The threshold question is whether this statute unreasonably distinguishes between persons who in fact constitute a “natural class.” See Reich v. State Highway Dep’t, 386 Mich. 617, 623, 194 N.W.2d 700, 702 (1972). From the city’s perspective, the statute treats alike anyone
