A Norwich Pharmacal Order (NPO) is a disclosure order which
allows information to be obtained from third parties who have
become 'mixed up' in wrongdoing, helping individuals to
investigate, pursue those ultimately responsible and (hopefully)
recover their losses.
NPOs are often used where a victim of wrongdoing does not know
the identity of the wrongdoer but can point to a third party who
has this information. They can also be used to trace assets and
obtain other information needed by the victim to put together its
case against the wrongdoer.
Such orders can be made when it is necessary to do justice,
whether against a third party to an action or potential action, or
a person who is a potential party to an action but is not yet
because none has been instituted. They are not a tool to be used
for the purposes of a "fishing expedition".
