EXEQUATUR, internat. law. A declaration made by the executive of a 
government near to which a consul has been nominated and appointed, after 
such nomination and appointment has been notified, addressed to the people, 
in which is recited the appointment of the foreign state, and that the 
executive having approved of the consul as such, commands all the citizens 
to receive, countenance, and, as there may be occasion, favorably assist the 
consul in the exercise of his place, giving and allowing him all the 
privileges, immunities, and advantages, thereto belonging. 3 Chit. Com. Law, 
56; 3 Maule & Selw. 290; 5 Pardes. 1445. 

EXEQUATUR, French law. This Latin word was, in the ancient practice, placed 
at the bottom of a judgment emanating from another tribunal, and was a 
permission and authority to the officer to execute it within the 
jurisdiction of the judge who put it below the judgment. 
     2. We have something of the same kind in our practice. When a warrant 
for the arrest of a criminal is issued by a justice of the peace of one 
county, and he flies into another, a justice of the latter county may 
endorse the warrant and then the ministerial officer may execute it in such 
county. This is called backing a warrant.
