Diane Duero represents companies and manufacturers in the defense of complex commercial, product liability, and class action litigation with an emphasis on consumer products and services.

Cases

Class Actions

Successfully represented a major telecommunications company in an MDL involving 18 underlying consumer, securities, and derivative class actions, together with over 20,000 mass arbitration claims that challenged the company's marketing and sales practices.

Won summary judgment against a certified, seven-state class action alleging false labeling and breach of warranty.

Defeated class certification amid allegations that two million Whirlpool-made ovens were prone to overheat. Disqualified the plaintiffs' expert witness and successfully argued that the claims were overly broad and the plaintiffs' purported theories for failure were too many to achieve certification.

Commercial Litigation

Won on behalf of a home appliance trade association in a complex federal constitutional case challenging state legislation on First Amendment grounds.

Other

Won before the Colorado Supreme Court in a fast-moving original jurisdiction case for the Colorado Independent Congressional Redistricting Commission. The decision sets critical precedent affirming the Commission's constitutional independence to draw boundaries for Colorado's eight congressional districts before the 2022 election. We prevailed for the Commission against Colorado's legislature, governor, attorney general, and secretary of state.
