The obvious reasons for the exercise of territorial
jurisdiction, particularly relating to criminal law,
are that:

• The state where the crime is committed
generally has the strongest interest in
punishing the criminal

• The local forum is the most convenient
one, since the witnesses and other facilities
are most probably available there

• The offender is most likely to befound there

• To avoid the element of double jeopardy,
i.e., subjecting the person to two legal
systems at the same time.
