Plaintiffs contend that they are entitled to amend their complaint as a matter of course prior to the filing of a responsive pleading, pursuant to Rule 15(a) of the North Carolina Rules of Civil Procedure. The plaintiffs contend that the defendants’ Rule *71812(c) motion was not a responsive pleading and therefore they are entitled to amend after the court granted the Rule 12(c) motion in favor of defendants.
Rule 15(a) provides:
“Amendments. — A party may amend his pleading once as a matter of course at any time before a responsive pleading is served . . .
Plaintiffs argue that the motion to dismiss pursuant to Rule 12(c) was not a responsive pleading and cite Clardy v. Duke University, 299 F. 2d 368 (4th Cir. 1962) as authority. The court in Clardy, however, held that once a summary judgment motion is granted, the plaintiffs’ right to amend pursuant to Rule 15(a) is foreclosed. In Clardy, the plaintiff filed a medical malpractice action, alleging that on or before April 1955, he sustained brain damage as a result of the defendant’s negligent treatment. His complaint was filed on 22 July 1960. Defendants moved for a dismissal, or, in the alternative, for summary judgment, on the basis that the action was barred by the statute of limitations. The court granted summary judgment for defendants. Plaintiff moved to amend the complaint pursuant to Rule 15(a), contending that a motion for summary judgment was not a responsive pleading and that therefore he was entitled to amend the complaint as a matter of course. The court noted:
“[T]here is no requirement that a responsive pleading be served before moving for summary judgment. ... If it should be held that plaintiff could amend without leave after a hearing and the granting of summary judgment against him, the effect would be to clothe a litigant with the power, at any time, to reopen a case. . . . Rule 15(a) is not to be construed so as to render Rule 12 meaningless and ineffective.” Clardy, supra, at 369-370.
The court held that the plaintiff was not entitled to amend the complaint pursuant to Rule 15(a), once summary judgment had been entered in favor of the defendants. We hold that the granting of defendants’ motion to dismiss pursuant to Rule 12(c) of the North Carolina Rules of Civil Procedure foreclosed the plaintiffs’ right to amend their complaint pursuant to Rule 15(a).
*719The plaintiffs also contend that the court erred in refusing to set aside the Order of Dismissal on 7 November 1977. The order of the court entered on 7 November 1977, however, is not before this court. The plaintiffs appealed from the 5 December 1977 Order denying their motion to amend, they did not appeal from the 7 November 1977 order, and are therefore bound by that order. See, Haiduven v. Cooper, 23 N.C. App. 67, 208 S.E. 2d 223 (1974); 7 Moore’s Federal Practice, § 60.30.
 Plaintiffs also contend that the order dismissing their complaint should be set aside pursuant to Rule 60(b)(2) on the grounds that new evidence had been discovered. Rule 60(b)(2) provides:
“Relief from judgment or order.
* * *
(b) Mistakes; inadvertence; excusable neglect; newly discovered evidence; fraud, etc.— On motion and upon such terms as are just, the court may relieve a party or his legal representative from a final judgment, order, or proceeding for the following reasons:
* * *
(2) Newly discovered evidence which by due diligence could not have been discovered in time to move for a new trial under Rule 59(b); . .
Appellants, however, have failed to establish that the evidence could not have been discovered within ten days after judgment was entered on 7 November 1977. “[F]or relief to be granted under Rule 60(b)(2) the failure to produce the evidence at the [Rule 12(b) hearing] must not have been caused by the moving party’s lack of due diligence. The evidence must be such as was not and could not by the exercise of diligence have been discovered in time to present in the original proceeding.” 7 Moore’s Federal Practice § 60.23 at 273. In the case sub judice, the plaintiffs could have obtained a copy of the birth certificate prior to hearing, and therefore the plaintiffs were not entitled to the relief under Rule 60(b)(2). See, Grupen v. Thomasville Furniture Industries, 28 N.C. App. 119, 220 S.E. 2d 201 (1975), cert. denied 289 N.C. 297, 222 S.E. 2d 696 (1976). We find no merit in plaintiffs’ third contention.
*720  Plaintiffs finally contend that the complaint should not be dismissed because it alleged a defective statement of a good cause of action. Plaintiffs cite Woodruff v. State Farm Mutual Auto. Ins. Co., 260 N.C. 723, 133 S.E. 2d 704 (1963); Sale v. Johnson, Commissioner of Revenue, 258 N.C. 749, 129 S.E. 2d 465 (1963); and Gillikin v. Springle, 254 N.C. 240, 118 S.E. 2d 611 (1961) in support of their contention. These cases held that an action should not be dismissed on the basis that the facts alleged are insufficient to state a cause of action, if the plaintiff can allege facts to state a cause of action in an amendment to the complaint. In the case sub judice, however, the complaint was dismissed because the suit was filed after the statute of limitations had run, and not because of the manner in which the causes of action were set forth in the complaint.
