delivered the opinion of the court:
Thе sole issue in this case is whether an employee’s suit for a declaratory judgment that he is entitled to a pension, filed 13/2 years after retirement, is barred by the statute of limitations. We hold that it is and affirm the trial court’s granting of summary judgment for thе defendant.
The relevant facts in this case, as revealed by the pleadings and affidavits, are few. The plaintiff rеtired from the defendant’s employment on December 31, 1962. The defendant provides a pension plan for thosе employees who have worked for the company for 15 years. Whether the plaintiff met this requirement depends on whether he was laid off in 1949 or whether his employment at that time was terminated; if the former, then the period for which he was laid off is included in the computation of years of service. It is not clear whether the defendant informed the plaintiff in 1958 of the length of time of his accredited past service, but this question is not relevant to our determinatiоn. Likewise, it is also not clear if the plaintiff ever applied for the pension and, if so, whether the defendant ever affirmatively refused to pay; what is clear is that the defendant has never considered the plaintiff to be entitled to a pension and has never made any pension payments to him. If the plaintiff was entitled to a pension, he would have been entitled to receive payments commencing in January 1963.
Under section 16 of the Limitations Act (Ill. Rev. Stat. 1977, ch. 83, par. 17), which all parties concede to be applicable, action upon a written contract must be commenced within ten years after the cause of action accrued. The same statutе existed in 1963.
I.
If the plaintiff is entitled to a pension, then under the Pension Plan the payments would be made in installments until the datе of his death. Basically, the plaintiff relies on the well-established rule that where an obligation is payable by installmеnts, the statute of limitations runs against each installment from the time it becomes due, that is, from the time when an action might bе brought to recover it. (Light v. Light (1957),
We find this latter trend of authority to be persuasive. After all, as the court stated in Pfeifer v. Bell & Howell Co. (1977),
“Statutes of limitations are statutes of repose, designed to prevent recovery on stale demands. (Mosley v. Michael Reese Hospital (1964),49 Ill. App. 2d 336 ,199 N.E.2d 633 .) The purpose attendant to such statutes is not to shield a wrongdoer (Tom Oleskers Exciting World of Fashion, Inc. v. Dun and Bradstreet, Inc. (1975),61 Ill. 2d 129 ,334 N.E.2d 160 ), but is to provide the defendant with a sufficient opportunity to investigate the factors upon which his liability may be based while such evidence is still ascertainable. (Halberstadt v. Harris Trust & Savings Bank (1973),55 Ill. 2d 121 ,302 N.E.2d 64 .) Thus, the time limits imposed by these statutes require diligence in the initiation of actions before the facts upon which the suit has been based become obscure by reasons of lapse of time, the defective memory of witnesses, or the death or removal of witnesses. (Isham v. Cudlip (1962),33 Ill. App. 2d 254 ,179 N.E.2d 25 .)° # V
If the plaintiff is permitted to delay the filing of suit until, as hеre, the material witnesses are no longer available, the purpose of the statute of limitations will be ignorеd. Furthermore, this result is consistent with the result reached by this court in Kopel v. Board of Education (1971),
II.
The plaintiff also suggests that an issue of fact remains since it is not known whеn the plaintiff first applied for the pension payments, such application being a condition precеdent to the benefits being paid. However, it is well established that a cause of action accrues when a suit first may be maintained thereon (Pfeifer v. Bell & Howell Co. (1977),
For the foregoing reasons, the determination of the trial court that the plaintiff’s suit is barred by the statute of limitations is affirmed.
Affirmed.
