writ ref d n.r.e.). See: White v. Larson, supra. In this perspective, that malice constitutes an intentional and unlawful interference, then that is all that must be proven to establish a cause of action to recover actual damages. Actual malice (ill will, spite, evil motive, or purposing the injury of another) need not exist. Clements v. Withers, 437 S.W.2d 818 (Tex.1969); Herider Farms-El Paso, Inc. v. Criswell, 519 S.W.2d 473 (Tex.Civ.App.—El Paso 1975, writ ref'd n.r.e.).
In Armendariz v. Mora, 553 S.W.2d 400, 404 (Tex.Civ.App.—El Paso 1977, writ ref d n.r.e.), this Court held:
To maintain the action for interference with the contract, it must be established that (1) there was a contract subject to interference, (2) the act of interference was wiliul and intentional, (3) such intentional act was a proximate cause of Plaintiffs damage, and (4) actual damage or loss occurred.
The proof of these elements establishes a prima facie case of interference. It then becomes incumbent upon the part of the defendant to show that his acts were either justified or privileged. Armendariz v. Mora, supra. See: Herider Farms-El Paso, Inc. v. Criswell, supra. But see: White v. Larson, supra. In all cases, the act of interference must be without legal right or justifiable cause on the part of the defendant. White v. Larson, supra; Herider Farms-El Paso, Inc. v. Criswell, supra.
Interference embraces within its scope all intentional invasions of contractual relations, including any act injuring or destroying property and so interfering with the performance of the contract itself, regardless of whether breach of contract is induced. It presupposes knowledge of the plaintiffs interests or, at least, of facts that would lead a reasonable man to believe in their existence. Tippett v. Hart, 497 S.W.2d 606 (Tex.Civ.App.—Amarillo), writ ref’d n.r.e. per curiam, 501 S.W.2d 874 (1973).
According to the court in Light v. Transport Insurance Company, supra, at 439, interference is wrongful:
[I]f acts complained of do not rest on some legitimate interest or if there is sharp dealing or overreaching or other conduct below the behavior of fair men similarly situated _ (Emphasis added).
See: Leonard Duckworth, Inc. v. Michael L. Field & Company, 516 F.2d 952 (5th Cir.1975), citing to Light in application of Texas law. Compare: International Bank of Commerce of Laredo v. Union National Bank of Laredo, 653 S.W.2d 539 (Tex.App.—San Antonio 1983, writ ref’d n.r.e.), wherein there was no evidence that the alleged wrongdoer had acted under anything other than a good faith belief that it could exercise certain rights.
A justifiable business interest does not grant absolute privilege to interfere with a contractual relationship between others. Frank Coulson, Inc.-Buick v. General Motors Corporation, 488 F.2d 202, 206, (5th Cir.1974). In determining the propriety of interference, the court in Coulson noted that various factors must be weighed. It stated:
Various important factors have been identified, however, which relate to an appraisal of the private interests of the parties involved as well as to a consideration of the social utility of these private interests. The principal issue thus becomes whether the social benefits derived in permitting acts of intervention outweigh the harm to be expected therefrom.
The jury was instructed in the case now before us as follows:
[A]ny intentional invasion of, or interference with, property or property rights, causing injury without just cause or excuse, constitutes “interference.” It must be shown that the conduct was willful and intentional and actual malice need not be shown.
Arguably, the instruction misplaced the burden of proof by requiring FMC to show that acts of interference were without just
