I’m somewhat surprised this issue comes up as often as it does:

"Scholarly commentary has recognized that Pennsylvania law has been riven with ‘considerable confusion as to the nature of the covenant of good faith, when that covenant is implicated, and how claims arising from a breach of the covenant are enforced.’ Seth William Goren, Looking for Law in all the Wrong Places: Problems in Applying the Implied Covenant of Good Faith Performance, 37 U.S.F. L. Rev. 257, 258 (2003). As the parties’ discussion of the law illustrates, it has not always been clear ‘whether the covenant is implicated in every contractual relationship or only some . . . and whether a breach of the covenant of good faith gives rise to an independent cause of action or is merely a tool of contract interpretation.’ Id. at 260. According to Goren this confusion ‘derived from confusing the contract-tort of bad faith with breaches of the general covenant [of good faith] present in all contracts.’ Id. at 303. Whatever its source, this confusion has largely been resolved: ‘The majority of Pennsylvania cases through the 1990s to today . . . have refused to permit independent claims for breach of the covenant of good faith outside of an insurer-insured relationship. Thus, in general, a ‘breach of such covenant is a breach of contract action, not an independent action for a breach of a duty of good faith and fair dealing.” Id. (footnote omitted) (quoting Seiple v. Comty. Hosp. of Lancaster, No. 97-cv- 8107, 1998 U.S. Dist. LEXIS 5093, 1998 WL 175593, at (E.D. Pa. April 14, 1998) (‘Pennsylvania does not recognize a claim for breach of covenant of good faith and fair dealing as an independent cause of action.’)).

Recent case law confirms this as the prevailing rule in Pennsylvania. See, e.g., LSI Title Agency, Inc. v. Eval. Servs., Inc., 2008 PA Super 126, 951 A.2d 384, 391 (Pa. Super.2008), appeal denied, 960 A.2d 841 (Pa.2008) (citing cases holding that Pennsylvania does not recognize separate breach of contractual duty of good faith and fair dealing where that claim is subsumed by separately pled breach of contract claim.); JHE, Inc. v. SEPTA, No. 1790 NOV. TERM 2001, 2002 Phila. Ct. Com. Pl. LEXIS 78, 2002 WL 101894,1 at (Pa. Com. Pl. May 17, 2002) (”[T]he implied covenant of good faith does not allow for a claim separate and distinct from a breach of contract claim . . . [A] claim arising from a breach of the covenant of good faith must be prosecuted as a breach of contract claim, as the covenant does nothing more than imply certain obligations into the contract itself.’) (collecting cases from other jurisdictions adopting same rule) (emphasis in original); Commonwealth v. BASF Corp., No. 3127, 2001 Phila. Ct. Com. Pl. LEXIS 95, 2001 WL 1807788, at (Pa. Com. Pl. Mar.15, 2001) (‘Pennsylvania law does not allow for a separate cause of action for breach of either an express or implied duty of good faith, absent a breach of the underlying contract.’).

Federal courts construing Pennsylvania law have adhered to the same rule. See e.g., Chanel, Inc. v. Jupiter Group, Inc., Civ. No. 3:04-CV-1540, 2006 U.S. Dist. LEXIS 43363, 2006 WL 1793223, at (M.D .Pa., June 27, 2006) (agreeing and citing cases holding that claim for breach of good faith and fair dealing is not independent cause of action, but part of a breach of contract claim); In re K-Dur Antitrust Litig., 338 F. Supp.2d 517, 549 (D.N.J. 2004) (‘Although Pennsylvania imposes a duty of good faith and fair dealing on each party in the performance of contracts, there is no separate cause of action for breach of these duties . . . .’) (citations omitted); Blue Mt. Mushroom Co. v. Monterey Mushroom, Inc.., 246 F. Supp. 2d 394, 400-01 (E. D. Pa. 2002) (‘Pennsylvania law does not recognize a separate claim for breach of implied covenant of good faith and fair dealing.’); McHale v. NuEnergy Group, No. Civ. A. 01- 4111, 2002 U.S. Dist. LEXIS 3307, 2002 WL 321797, at (E.D. Pa. Feb.27, 2002) (internal citations omitted) (same)."

McHolme/Waynesburg, LLC v. Wal-Mart Real Estate Bus. Trust, No. 08-961, 2009 U.S. Dist. LEXIS 38934, at *5–8 (W.D. Pa. May 7, 2009).

I suppose from the plaintiff’s perspective it is an issue of "why not? If the claim is recognized, it could have been malpractice for me not to include it," but I wonder about the ramifications if a plaintiff actually gets one of these "independent" good faith claims through trial.

What are the elements of proving it? What are your damages? Do they overlap your breach of contract damages? Can you recover twice? 

Is there any doubt the defendant will appeal such a verdict? Any doubt it will get your case reversed and re-tried?

I think the down side including such a claim — particularly the distraction from the real issues in the case and the loss of some credibility with the court — outweigh any potential benefits.

Just include it as more evidence of the breach of contract.
