class action lawsuit集体诉讼

suit有官司的意思。至于suit和lawsuit是不是同意，这还得看你以哪国法律的角度来看。以我国法律的角度来说：因为我朝官方语言是汉语，所以既然在英汉辞典上，suit和lawsuit都有诉讼或官司的意思，那么suit和lawsuit是同意的。

litigation 更强调一个诉讼或者打官司的状态，这往往是一个长期的过程，例如：the company has been in ~~ with its previous auditor for a full year.lawsuit则更加强调诉讼这一动作这件事。例如：he filed a ~~ against his record company.
