The evidence considered in the light most favorable to plaintiff is sufficient to make out a prima facie case of technical assault *512or trespass upon the person of plaintiff. Therefore, the one question posed for decision is this: Is plaintiff’s cause of action barred by the one-year, G.S. 1-54 (8), or the three-year, G.S. 1-52 (5) statute of limitations ? We are constrained to answer in the affirmative.
The defendant demurred for that it appears upon the face of the complaint that plaintiff’s alleged cause of action is barred by the one-year and the three-year statutes of limitations. The demurrer was overruled. Even so, the order overruling the demurrer was not binding on the trial court on the motion for judgment as in case of nonsuit.
A demurrer to a complaint, G.S. 1-127, and a demurrer to the evidence, G.S. 1-183, are different in purpose and result. One challenges the sufficiency of the pleadings, the other the sufficiency of the evidence. Smith v. Sink, 211 N.C. 725, 192 S.E. 108; Law v. Cleveland, 213 N.C. 289, 195 S.E. 809; Montgomery v. Blades, 222 N.C. 463, 23 S.E. 2d 844; Coleman v. Whisnant, 226 N.C. 258, 37 S.E. 2d 693.
Furthermore, the demurrer on the grounds assigned was an improper and unwarranted pleading. The statutes of limitations can never be taken advantage of by demurrer. Guthrie v. Bacon, 107 N.C. 337; Bacon v. Berry, 85 N.C. 124; King v. Powell, 127 N.C. 10; Oldham v. Rieger, 145 N.C. 254; Logan v. Griffith, 205 N.C. 580, 172 S.E. 348. “The objection that the action was not commenced within the time limited can only be taken by answer.” G.S. 1-15.
Although the plea of a statute of limitations in bar of plaintiff’s right to recover places the burden on plaintiff to show that the action was instituted within the time allowed by the pleaded statute, Allsbrook v. Walston, 212 N.C. 225, 193 S.E. 151; Muse v. Muse, ante, 182, there is no time limitation on the right of such plaintiff to prosecute his cause until and unless the statute is expressly pleaded in the answer.
Plaintiff stressfully contends, however, that in any event she did not ascertain that the alleged tort upon which she relies had been committed until she consulted Dr. Welton in 1951, and that the statute began to run as of that date. But the statute itself fixes the date upon which the statutes began to run. “Civil actions can only be commenced within the periods prescribed in this chapter, after the cause of action has accrued, except where in special cases a different limitation is prescribed by statute.” G.S. 1-15. And the only “special case” in respect to torts “where a different limitation is prescribed by statute” is contained in the three-year statute, G.S. 1-52. This “different limitation” relates only to actions grounded on allegations of fraud or mistake. G.S. 1-52 (9). Consequently it has no application here.
Furthermore, we have heretofore expressly held that lack of knowledge on the part of plaintiff does not suspend the statute. Gordon v. Fredle, 206 N.C. 734, 175 S.E. 126.
*513Tbe plaintiff in ber amended complaint alleges tbat defendant “wrongfully, knowingly, fraudulently and unlawfully concealed and withheld from tbe plaintiff tbe fact tbat be bad ligated . . . both Fallopian tubes and thereby completely and permanently rendered tbe plaintiff sterile . . . which this plaintiff did not and could not . . . have discovered except as herein alleged.” She now contends tbat tbe alleged fraudulent concealment suspended tbe statute which, under tbe circumstances, began to run on tbe day in 1951 she actually ascertained tbe facts.
On tbe questions whether (1) tbe lack of knowledge of a cause of action postpones tbe commencement of tbe period of limitation until tbe facts are discovered, 34 A.J. 186, or (2) tbe fraudulent concealment of tbe facts constitutes an implied exception to tbe statutes of limitations, postponing tbe commencement of tbe running of tbe statute until discovery or opportunity to discover tbe facts, tbe courts are divided in opinion. See cases cited in 34 A.J. 186, n. 17, and p. 188, n. 13.
As stated, our statute fixes tbe commencement date of our statutes of limitations, and this Court has already adopted tbe majority view tbat tbe mere lack of knowledge of tbe facts constituting a cause of action does not postpone tbe running of tbe statute. Gordon v. Fredle, supra.
Whether tbe fraudulent concealment of tbe facts by tbe tort-feasor constitutes an implied exception to tbe statute, notwithstanding its express language, we need not now decide for tbe reason plaintiff offered no evidence to support ber allegation of fraudulent concealment. Indeed, she testified tbe only time she saw tbe defendant was in tbe operating room, tbat be did not visit ber in tbe hospital either before or after tbe operation, and she did not thereafter consult him about ber condition or tbe operation be performed. .
Since tbe alleged tort was committed in 1944 and summons in this action was issued 25 August 1951, tbe plaintiff’s cause of action is barred by tbe three-year, G.S. 1-52 (5), if not tbe one-year, G.S. 1-54 (3), statute of limitations. Therefore tbe judgment dismissing tbe action as in ease of nonsuit is
Affirmed.
