California Penal Code 236 PC describes the crime of false imprisonment as unlawfully depriving another person of their personal liberty. Put simply, it's a crime to detain, restrain, or confine someone without their consent and not allow them to leave when they want.
If you are referring to the tort of false imprisonment, then the answer is yes. You can file a civil lawsuit against someone or an entity that falsely imprisoned you. However, outside of an extreme situation, the problem is that there are rarely any actual damages. Therefore, a lawsuit is rarely worth doing.
