In Fong Yue Ting, the United States Supreme Court used these words:
"Strictly speaking, transportation, extradition, and deportation, although each has the effect of removing a person from the country, are different things, and have different purposes.
"Transportation is by way of punishment of one convicted of an offence against the laws of the country. Extradition is the surrender to another country of one accused of an offence against its laws, there to be tried, and, if found guilty, punished.
"Deportation is the removal of an alien out of the country, simply because his presence is deemed inconsistent with the public welfare and without any punishment being imposed or contemplated either under the laws of the country out of which he is sent or of those of the country to which he is taken."
In Reference re Persons of Japanese Race, Justice Estey of Canada's Supreme Court adopted these words:
"Deportation ... as it is applied in law it is a compulsory sending out of, or ... a forcible removal."
In R v Secretary of State for Foreign Affairs and Secretary of State for Colonies, Justice Jenkins wrote:
"The word deportation has implicit in it the taking of the person in question from the country from which he is deported to some other place"
The grounds for deportation varies from country to country.
