Rule 48, which is one of the federal rules of civil procedure, determines the number of jurors as well as what constitutes a verdict and how to conduct jury polling, required for a civil litigation trial, states Legal Information Institute. This rule was first amended in 1991 when the original 1937 rule became obsolete pursuant to the adoption by many individual states of the number six as the minimum required number of jurors.
According to Title I, Rule 1, the rules of civil procedure exist to ensure fair, quick and affordable resolution of noncriminal lawsuits, as listed by Legal Information Institute. Title IV, Rule 23 states the rules under which class actions may be brought, including what constitutes a class and under what circumstances a suit may be brought and judgment rendered.
The federal rules of civil procedure, as amended effective Dec. 1, 2015, cover a range of topics from Title I, rules that govern the scope and purpose of civil procedures, to Title XIII, additional rules for maritime civil procedures, according to Legal Information Institute. State courts, however, follow their own rules and procedures. The rules of civil procedure at the federal or state level control how civil trials are conducted.
