Amendment Seven to the Constitution was ratified on December 15, 1791. It protects the right for citizens to have a jury trial in federal courts with civil cases where the claim exceeds a certain dollar value. It also prohibits judges in these trials from overruling facts revealed by the jury.
Ing to the Supreme Court, the jury-trial right applies only when "serious" offenses are at hand—petty offenses don't invoke it. For purposes of this right, a serious offense is one that carries a potential sentence of more than six months' imprisonment.
Any party may demand a trial by jury of any issue triable of right by a jury by (1) serving upon the other parties a demand therefor in writing at any time after the commencement of the action and not later than 10 days after the service of the last pleading directed to such issue, and (2) filing the demand as required ...
The constitution grants a defendant the right to a 'speedy trial'. Sometimes, the court system can be frustratingly slow when it comes to finishing up a case. A jury trial demand is simply a request that a date be set for a jury trial.

Predictable Outcomes: Judges' decisions are generally more predictable than those of a jury, in which emotions or personal biases can sway. If, for example, you're assigned a judge with a record of showing leniency for mitigating circumstances, your attorney might recommend waiving the jury trial.
Defendants generally trust that a jury will acquit or render a not guilty verdict more often (than a judge). The O.J. trial certainly validated this belief. Both the defendant and the People have the right to a jury trial in misdemeanor and felony trials (California Constitution, Article I, § 16 and Penal Code § 699).
