arbitration (iir-bi-tra'shon), it. [< ME. arbitra- 
cion, < OF. arbitration = Pr. arbitracio, < L. 
arbitratio(ti-), < arliitrari, arbitrate, judge: see 
arbitrate.'] The hearing and determining of a 
cause between parties in controversy by a per- 
son or persons chosen or agreed to by the par- 
ties. This may he done by one person, but it is usual to 
ehoose more than one. Frequently two are nominated, 
one by eaeh party, the two being authorized in turn to 
agree upon a third, who is called the umpire (or, in Scot- 
land, sometimes the oeemnan), and who either acts with 
them or is called ou to decide in case the primary arbitra- 
tors differ. The determination of arbitrators or umpires 
is called an aicttrd. By the common law an award prop- 
erly made is binding; but the arbitrators' authority may 
be revoked before award at the will of either party. Per- 
manent boards of arbitration are sometimes constituted 
bylegislative or corporate authority, but the submission of 
cases to their decision is always voluntary. 
It is not too much to hope that arbitration and concilia- 
tion will be the means adopted alike by nations and by 
individuals, to adjust all differences.
