You already know that lawsuits fall into two categories. Some are civil cases. Some are criminal cases. However, you probably do not have a clear idea as to the distinction between the two. A few general comments can help you see the difference.
In civil cases, the party starting the lawsuit is known as the "plaintiff". The person against whom the suit is brought is called the "defendant". Plaintiff’s suit is commenced by service of two documents, a Summons and a Complaint, upon the defendant. The Summons does what its name suggests; it summons or "calls" the defendant before the court. The Complaint is perhaps the more important document. In the Complaint, the plaintiff makes allegations or "accusations" against the defendant. The plaintiff’s Complaint will charge the defendant either with causing bodily injury or property damage or with depriving the plaintiff of some thing of value to which the plaintiff believes he’s is entitled. The Complaint will also request the court to award "damages", that is, money to the plaintiff to compensate him for his bodily injury or property damages or the thing of which he has been deprived. The defendant responds to the Complaint by filing a document called an Answer. These papers, called the pleadings, have been exchanged between the parties sometime before the trial starts.
The foregoing describes a very simple civil case. Often, civil cases are more complicated. You may be selected as juror in a civil case where there are several plaintiffs or several defendants. Or, in addition to the request by the plaintiff for money damages, the defendant may also be requesting money damages either from the plaintiff in what is called a "counter-claim," or from another defendant, called a "cross-claim," or from a person not originally involved in the case but later added and called a "third party defendant." Moreover, it must be remembered that the plaintiff and the defendant are not always individuals. They may be partnerships or corporations. Even the city, county, state, or federal government may be a party to a civil action.
In criminal cases, the party starting the lawsuit is always "The People: acting through governmental representatives, such as the County Prosecuting Attorney, when a violation of State law is alleged, or the City Attorney, when a violation of a City ordinance is alleged.
All crimes are prosecuted in the name of the appropriate governmental body, for when a crime is committed, it is the law of the state that is broken and the offense is against the people of the state, not just against one or more individuals as in a civil case. The purpose of a criminal case is to determine whether or not the defendant violated one or more of our statutory laws. Prior to the trial, a complaint is prepared and filed setting forth one or more charges against the defendant. Several charges may be combined in one such complaint but each is separately stated and is called a count. For example, a complaint may charge in one count that the defendant robbed the complainant, while in a second count, it may charge that the defendant also assaulted and beat the complainant.
After the charge or charges are filed, but before the trial, the defendant is arraigned. That is, he is brought before the judge and the complaint is read to him. For each violation charged he is asked, "How do you plead?" And he pleads "guilty" or "not guilty."
There are other, very important, differences between civil and criminal cases. These differences are not discussed in this booklet, but the specific rules which will apply to the trial in which you participate as a juror, whether civil or criminal, will be explained carefully to you by the judge. If you do not understand or if you have any questions about any of the Judge’s instructions, you should not only feel entirely free, but duty -bound to ask the judge to explain further.
