A recent rule change regulating the amount of money spent on discovery in federal court could diminish the chances of success for plaintiffs with limited resources going up against big corporations or otherwise financially-powerful defendants, some lawyers observed.

Ballard Spahr partner Philip N. Yannella said discovery should be limited in low-dollar claim cases. Leader of the firm's e-discovery group, Yanella said that in those cases, "the amount in controversy isn't that high; you would expect the amount of discovery needed is less than in a class action or mass tort context."
