      [1913 Webster]
    
from Bouvier's Law Dictionary, Revised 6th Ed (1856)
DEVIATION, insurance, contracts. A voluntary departure, without necessity, 
or any reasonable cause, from the regular and usual course of the voyage 
insured. 
     2. From the moment this happens, the voyage is changed, the contract 
determined, and the insurer discharged from all subsequent responsibility. 
By the contract, the insurer only runs the risk of the contract agreed upon, 
and no other; and it is, therefore, a condition implied in the policy, that 
the ship shall proceed to her port of destination by the. shortest and 
safest course, and on no account to deviate from that course, but in cases 
of necessity. 1 Mood. & Rob. 60; 17 Ves. 364; 3 Bing. 637; 12 East, 578. 
     3. The effect of a deviation is not to vitiate or avoid the policy, but 
only to determine the liability of the underwriters from the time of the 
deviation. If, therefore, the ship or goods, after the voyage has commenced, 
receive damage, then the ship deviates, and afterwards a loss happen, there, 
though the insurer is discharged from the time of the deviation, and is not 
answerable for the subsequent loss, yet he is bound to make good the damage 
sustained previous to the deviation. 2 Lord Raym. 842 2 Salk. 444. 
     4. But though he is thus discharged from subsequent responsibility, he 
is entitled to retain the whole premium. Dougl. 271; 1 Marsh. Ins. 183; 
Park. Ins. 294. See 2 Phil. Ev. 60, n. (b) where the American cases are 
cited. 
     5. What amounts to a deviation is not easily defined, but a departure 
from the usual course of the voyage, or remaining at places where the ship 
is authorized to touch, longer than necessary, or doing there what the 
insured is not authorized to do; as, if the ship have merely liberty to 
touch at a point, and the insured stay there to trade, or break bulk, it is 
a deviation. 4 Dall. 274 1 Peters' C. C. R. 104; Marsh. Ins. B. 1, c. 6, s. 
2. By the course of the voyage is not meant the shortest course the ship can 
take from her port of departure to her port of destination, but the regular 
and customary track, if such there be, which long us usage has proved to be 
the safest and most convenient. 1 Marsh. Ins. 185. See 3 Johns. Cas. 352; 7 
T. R. 162. 
     6. A deviation that will discharge the insurer, must be a voluntary 
departure from the usual course of the voyage insured, and not warranted by 
any necessity. If a deviation can be justified by necessity, it will not 
affect the contract; and necessity will justify a deviation, though it 
proceed from a cause not insured against. The cases of necessity which are 
most frequently adduced to justify a departure from the direct or usual 
course of the voyage, are, 1st. Stress of weather. 2d. The want of necessary 
repairs. 3d. Joining convoy. 4th. Succouring ships in distress. 5th. 
Avoiding capture or detention. 6th. Sickness of the master or mariner. 7th. 
Mutiny of the crew. See Park, Ins. c. 17; 1 Bouv. Inst. n. 1187, et seq.; 2

DEVIATION, contracts. When a plan has been adopted for a building, and in 
the progress of the work a change has been made from the original plan, the 
change is called a deviation. 
     2. When the contract is to build a house according to the original 
plan, and a deviation takes place, the contract shall be traced as far as 
possible, and the additions, if any have been made, shall be paid for 
according to the usual rate of charging. 3 Barn. & Ald. 47; and see 1 Ves. 
jr. 60; 10 Ves. jr. 306; 14 Ves. 413; 13 Ves. 73; Id. 81 6 Johns. Ch. R. 38;

Pick. 298. 
     3. The Civil Code of Louisiana, art. 2734, provides, that when an 
architect or other workman has undertaken the building of a house by the 
job, according to a plot agreed on between him and the owner of the ground, 
he cannot claim an increase of the price agreed on, on the plea of the 
original plot having been changed and extended, unless he can prove that 
such changes have been made in compliance with the wishes of the proprietor.
