- adversary procedure
In Anglo-American law, the principal method of offering evidence in court.It requires the opposing sides to present pertinent information and to introduce and cross-examine witnesses before a jury and/or a judge. Each side must conduct its own investigation. In criminal proceedings, the prosecution represents the government and has at its disposal the police department with its investigators and laboratories; the defense must arrange and pay for its own investigation. (Legal aid is available for the poor.) In civil (noncriminal) proceedings the adversary system works similarly, except that both sides engage private attorneys to prepare their cases. Skillful questioning often produces testimony that can be interpreted in various ways; in cross-examination, lawyers seek to alter the jury's initial perception of the testimony.

This procedure is observed primarily in countries in which the Anglo-American legal system of common law predominates.Under the adversary system, each side is responsible for conducting its own investigation. In criminal proceedings, the prosecution represents the people at large and has at its disposal the police department with its investigators and laboratories, while the defense must find its own investigative resources and finances. Both sides may command the attendance of witnesses by subpoena (q.v.). If the defendant is indigent, his attorney's opportunities for a broader investigation are limited by the provisions of the jurisdiction in which the trial is conducted. In criminal law under the adversary system, the accused need not be present in grand jury indictment proceedings (no longer conducted in Great Britain and recommended by some authorities for eventual abolition in the United States). If an indictment is handed down by the grand jury, its proceedings are available to the defendant. Under civil law the adversary system works similarly, except that both plaintiff and respondent must prepare their own cases, usually through privately engaged attorneys.In any adversary trial, the opposing sides present evidence, examine witnesses, and conduct cross-examinations, each in an effort to produce information beneficial to its side of the case. Skillful questioning can often produce testimony that can be made to take on various meanings. What seemed absolute in direct testimony can raise doubts under cross-examination. The skills of the attorneys are also displayed at the time of summation, especially in a jury trial, when their versions of what the jury has heard may persuade the jury to interpret the facts to the benefit of the side that is most persuasive.In adversary proceedings before juries the judge functions as moderator and referee on points of law, rarely taking part in the questioning unless he or she feels that important points of law or fact must be made clearer. In a bench trial (without a jury) the judge makes findings of fact as well as of law.
