Did Nair win the case

There appears to be confusion regarding a "Nair case" directly related to Jallianwala Bagh. The historical records show that Sir Chimanlal Harilal Setalvad and other Indian lawyers presented arguments during the Hunter Committee inquiry (1919-1920) that investigated the massacre, but there was no famous lawyer specifically named Nair who fought a landmark case about this incident. The Hunter Committee itself was divided in its conclusions, with British members largely defending General Dyer's actions while Indian members condemned them as excessive and inhumane.

If the question refers to any modern legal proceedings or fictional representations in films related to Jallianwala Bagh, it's important to note that the actual historical legal aftermath saw limited justice. General Dyer was removed from service but never criminally prosecuted, and no compensation was adequately provided to victims' families. The failure to achieve proper legal justice through British courts became one of the key grievances that fueled India's independence movement. Any specific case involving someone named Nair would need additional context to accurately address whether it was won or lost, as this name doesn't appear prominently in the established historical record of Jallianwala Bagh legal proceedings.
