Multiple defendants-single count (MSC) is a legal term used to describe a situation in which multiple defendants are named in a single criminal charge. This means that all the defendants are being charged with the same criminal act, even if they have different roles in the act. There are two main types of MSC: joint and several liabilities and collective liability. Joint and several liability means that the defendants are all responsible for the same criminal act and can be held liable for the entire sum of the damages, regardless of the role each defendant played. Collective liability means that each defendant is only responsible for their own actions and not the actions of the other defendants. This means that any damages awarded by the court will be divided among the defendants based on their individual roles in the criminal act.
