Murphy is co-lead counsel to the named plaintiff in a consumer class action on behalf of homeowners who were pursued by the defendant debt collector for unpaid homeowner association fees. "The Legislature passed restrictions on what an HOA can do in the way of charging interests, fees and fines when a homeowner is late [paying] homeowner dues." The legislation, the Davis-Sterling Act, was created "to protect homeowners that get so far behind that they can lose their home." Pro Solutions is a third party debt collector that offers its services to HOAs for free. "Third party debt collectors have taken a position that they are not subject to the Davis-Sterling Act so they [charge] unfettered fees and penalties." Along with co-counsel from Housing and Economic Rights Advocates, Murphy successfully opposed defendant's motion to dismiss in July 2014. Hanson v. Pro Solutions, CV13-05377 (N.D. Cal., filed Nov. 19, 2013).

She is also representing the named plaintiff in a class action against Best Buy Co. Inc. The plaintiff alleges the representations of the battery life of laptops sold by Best Buy are misleading. At issue is "the represented battery life because in many cases manufacturers, [like Toshiba and Dell], are having their laptops battery life determined by a third party protocol call m007." This testing protocol can result in the battery life being misstated by a factor of 2, according to Murphy. She and co-counsel seek to certify a class of Best Buy laptop purchasers.
