This document provides an overview of product liability, litigation in India, and class action suits in the US. It defines product liability as holding manufacturers responsible for injuries caused by their products. The main types of product liability claims are negligence, strict liability, and breach of warranty. Litigation in India includes public interest litigation which allows courts or private parties to file cases on behalf of the public. Class action suits originated in the US and allow large groups of people to collectively sue defendants. They can increase efficiency and incentivize individuals who otherwise wouldn't pursue small claims.
