Collateral estoppel (CE), known in modern terminology as issue preclusion, is a common law estoppel doctrine that prevents a person from relitigating an issue. One summary is that, "once a court has decided an issue of fact or law necessary to its judgment, that decision ... preclude[s] relitigation of the issue in a suit on a different cause of action involving a party to the first case". The rationale behind issue preclusion is the prevention of legal harassment and the prevention of overuse or abuse of judicial resources.
Estoppel is a judicial device in common law legal systems whereby a court may prevent or "estop" a person from making assertions or from going back on his or her word; the person being sanctioned is "estopped". Estoppel may prevent someone from bringing a particular claim. Legal doctrines of estoppel are based in both common law and equity. It is also a concept in international law.

The posting rule is an exception to the general rule of contract law in common law countries that acceptance of an offer takes place when communicated. Under the posting rule, that acceptance takes effect when a letter is posted. In plain English, the "meeting of the minds" necessary to contract formation occurs at the exact moment word of acceptance is sent via post by the person accepting it, rather than when that acceptance is received by the person who offered the contract.
Offer and acceptance are generally recognised as essential requirements for the formation of a contract, and analysis of their operation is a traditional approach in contract law. The offer and acceptance formula, developed in the 19th century, identifies a moment of formation when the parties are of one mind. This classical approach to contract formation has been modified by developments in the law of estoppel, misleading conduct, misrepresentation, unjust enrichment, and power of acceptance.
R v Ron Engineering and Construction (Eastern) Ltd, of 1981 is the leading Supreme Court of Canada decision on the law of tendering for contracts. The case concerned the issue of whether the acceptance of a call for tenders for a construction job could constitute a binding contract. The Court held that indeed in many cases the submission of an offer in response to a call for tenders constitutes a contract separate from the eventual contract for the construction. With the release of the decision, the tendering process practiced in Canada was fundamentally changed.

Commonwealth v Verwayen, also known as the Voyager case, is a leading case involving estoppel in Australia. Bernard Verwayen sued the Australian government for damages caused by a collision between two ships of the Australian Navy. A representative of the Government initially indicated to Bernard Verwayen that the Government would not raise the statute of limitations as a defence to their negligence. In court however, the Government relied on this defence. While the decision of the High Court was split, a majority of judges found that the Government could not rely on this statement as a defence. Justices Toohey and Gaudron came to this conclusion on the basis that the Government had waived their right to rely on this defence. However, Justices Deane and Dawson came to this conclusion under the doctrine of estoppel, which provides that a defendant can not contradict a previous representation or promise made that has established an assumed state of legal affairs. This case is most frequently referred to in relation to its influence on the doctrine of estoppel.
