Nation
A group or race of people that share history, traditions and culture. The United Kingdom is comprised of four nations or national groups: the English, Scots, Irish and Welsh. Canada includes French-Canadians, English-Canadians and a number of aboriginal nations. Thus, states may be comprised of one or several nations. It is common English to use the word "nation" when referring to what is known in law as "states."

National treatment
A tenet of international trade agreements whereby nations must afford imported goods the same treatment that they afford domestic or "national" products (no discrimination).

Natural justice
A word used to refer to situations where audi alteram partem (the right to be heard) and nemo judex in parte sua (no person may judge their own case) apply. The principles of natural justice were derived from the Romans who believed that some legal principles were "natural" or self-evident and did not require a statutory basis. These two basic legal safeguards govern all decisions by judges or government officials when they take quasi-judicial or judicial decisions.

NCND Agreement
An international trade instrument; "non circumvention/non disclosure agreement" used in the preliminary stages of a business transaction where the Seller and Buyer do not know each other, but are brought into contact with each other by one or more intermediaries (also known as brokers or middlemen), to fulfill the transaction. Non Circumvention/Non Disclosure Agreements ensure that the intermediaries in the transaction are not cicumvented and excluded from the transaction by the Buyer and/or Seller and/or the other intermediaries. Many trade transactions are chain-like. Product flows like this: seller-broker-broker-broker-buyer. The brokers in the middle use NCNDs to ensure that they are not circumvented by anyone else in the chain; also, to ensure that information on the other parties in the chain is not disclosed to outside parties. They are valid for a specified term; usually two years.

Negligence
Not only are people responsible for the intentional harm they cause, but their failure to act as a reasonable person would be expected to act in similar circumstances (i.e. "negligence") will also give rise to compensation. Negligence, if it causes injury to another, can give rise to a liability suit under tort. Negligence is always assessed having regards to the circumstances and to the standard of care which would reasonably be expected of a person in similar circumstances. Everybody has a duty to ensure that their actions do not cause harm to others. Between negligence and the intentional act there lies yet another, more serious type of negligence which is called gross negligence. Gross negligence is any action or an omission in reckless disregard of the consequences to the safety or property of another. See also contributory negligence and comparative negligence.

Negotiate
To communicate on a matter of disagreement between two parties, with a view to first listen to the other party's perspective and to then attempt to arrive at a resolution by consensus.

Nemo judex in parte sua

Non est factum
Latin for "not his deed" and a special defense in contract law to allow a person to avoid having to respect a contract that she or he signed because of certain reasons such as a mistake as to the kind of contract.
