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.
Contract
Less common are unilateral contracts in which one party makes a promise, but the other side does not promise anything. In these cases, those accepting the offer are not required to communicate their acceptance to the offeror. In a reward contract, for example, a person who has lost a dog could promise a reward if the dog is found, through publication or orally. The payment could be additionally conditioned on the dog being returned alive. Those who learn of the reward are not required to search for the dog, but if someone finds the dog and delivers it, the promisor is required to pay. In the similar case of advertisements of deals or bargains, a general rule is that these are not contractual offers but merely an "invitation to treat" (or bargain), but the applicability of this rule is disputed and contains various exceptions. The High Court of Australia stated that the term unilateral contract is "unscientific and misleading".
