The phrase that can replace the underlined phrase in the sentence with domain-specific terminology is ‘class action lawsuit’. In such a lawsuit, multiple plaintiffs with similar grievances against a company are grouped into a single case. Class action suits are particularly important when addressing widespread harm caused by a company's products, as they consolidate individual claims into one larger, more efficient legal action. This not only allows cost-sharing among plaintiffs but also encompasses individuals who might not be aware that they have a potential legal case. Class action lawsuits are often noted in legal books and considered significant enough to be discussed in American history classes due to their societal impact.
