Plea bargain
Plea bargain as a formal legal provision was introduced in Pakistan by the National Accountability Ordinance 1999, an anti-corruption law. A special feature of this plea bargain is that the accused applies for it, accepting guilt, and offers to return the proceeds of corruption as determined by investigators/prosecutors. After an endorsement by the Chairman National Accountability Bureau, the request is presented before the court, which decides whether it should be accepted or not. If the request for plea bargain is accepted by the court, the accused stands convicted but neither is sentenced if in trial nor undergoes any sentence previously pronounced by a lower court if in appeal. The accused is disqualified to take part in elections, hold any public office, or obtain a loan from any bank; the accused is also dismissed from service if a government official.
Pleading
In its final form in the 19th century, common law pleading was terribly complex and slow by modern standards. The parties would normally go through several rounds of pleadings before the parties were deemed to have clearly stated their controversy, so that the case was "at issue" and could proceed to trial. A case would begin with a complaint in which the plaintiff alleged the facts entitling him to relief, then the defendant would file any one of a variety of pleas as an answer, followed by a replication from the plaintiff, a rejoinder from the defendant, a surrejoinder from the plaintiff, a rebutter from the defendant, and a surrebutter from the plaintiff. At each stage, a party could file a demurrer to the other's pleading (essentially a request that the court immediately rule on whether the pleading was legally adequate before they had to file a pleading in response) or simply file another pleading in response.
