discovery of the wrongful act, occurred in September 1978, just slightly more than a month before the declaration was filed. In addition, if the discovery rule is adopted in these circumstances, the negligence action would also have been timely filed. Although the "republication” theory adopted by the district court would be applicable only to a defamation action, this would not be true with respect to the discovery rule.
Consistent with the authorization in the certification order, we do not answer the questions as phrased in that order. Instead, based upon our analysis of the declaration, we shall deal with the underlying issue in terms of the discovery rule. We hold that in a tort action grounded upon facts such as alleged in the declaration here, the cause of action for purposes of limitations, whether sounding in libel or negligence, accrues when the plaintiff knew or reasonably should have known that the defendant committed a wrongful act which injured or damaged the plaintiff. Since, under the allegations in this case, the plaintiff did not know, and reasonably should not have known, of this until September 1978, neither cause of action is barred by limitations. In light of our holding, we need not, and thus do not, decide whether limitations in a libel action begin to run anew upon a republication which is the natural and probable consequence of the original publication.
As this Court has pointed out on numerous occasions, a tort cause of action normally accrues for limitations purposes when the wrongful act occurs, because "[o]rdinarily, a potential tort plaintiff is immediately aware that he has been wronged.” Harig v. Johns-Manville Products, 284 Md. 70, 76, 394 A.2d 299 (1978). Nevertheless, long ago the Court recognized, and has continued to recognize, that fairness to a plaintiff who has not slept on his rights justifies exceptions to this general rule. Thus in Belt v. Marriott, 9 Gill. 331, 338 (1850), it was indicated that, although the statute of limitations in an action of trover ordinarily begins to run from the conversion, the rule would be different if the plaintiff were unable to discover the
