these cases relied on the principle first enunciated in the seminal case of P., W. & B. R.R. Co. v. Hoeflich, 62 Md. 300, 307 (1884), in which our predecessors said:
“. . . The force and deliberation with which the wrongful act is done, are not necessarily the tests by which the question of punitive damages is to be determined. On the contrary, to entitle one to such damages there must be an element of fraud, or malice, or evil intent, or oppression entering into and forming part of the wrongful act. It is in such cases as these that exemplary or punitive damages are awarded as a punishment for the evil motive or intent with which the act is done, and as an example or warning to others. . . .” (emphasis added).
A corollary to this rule is that “where the act, although wrongful in itself, is committed in the honest assertion of a supposed right — or in the discharge of duty, or without any evil or bad intention, there is no ground on which such damages can be awarded.” P., W. & B. R.R. Co. v. Hoeflich, supra, 62 Md. at 307; Accord, Siegman v. Equitable Trust Co., supra, 267 Md. at 314; Associates Discount v. Hillary, supra, 262 Md. at 580; Dennis v. Baltimore Transit Co., 189 Md. 610, 617, 56 A. 2d 813 (1948).
Much of the discussion in the recent decisions on this question has dealt with whether the malice must be actual — sometimes called express — or can be its legal equivalent, frequently labeled implied malice. See, e.g., Smith v. Gray Concrete Pipe Co., supra; Drug Fair v. Smith, supra; St. Paul at Chase v. Mfrs. Life Insur., 262 Md. 192, 238-39, 278 A. 2d 12 (1971), cert. denied, 404 U. S. 857 (1971); Conklin v. Schillinger, 255 Md. 50, 71, 257 A. 2d 187 (1969). Actual or express malice — at least in this context — has been characterized as the performance of an act without legal justification or excuse, but with an evil or rancorous motive influenced by hate, the purpose being to deliberately and willfully injure the plaintiff.
