We begin with creditors because (1) creditors are the only constituency that still has some remnants of protections in corporate law, and (2) most other claims ultimately resolve into damages or other financial claims, transforming all constituencies into creditors at the end of the day.
Gheewalla sets forth the principle that creditors cannot invoke the protections of fiduciary duties against corporate directors (although they may occasionally have standing to enforce a derivative claim on behalf of the corporation). MetLife v. RJR Nabisco declines to protect the plaintiff-creditor under a contractual implied duty of good faith and fair dealing. The bottom line is that creditors have to rely on contractual protections. The MetLife decision reviews many customary protective clauses.
Do you find the courts' reasonings convincing?
