   Propriety of manner or conduct; grace arising from

   or to the place and occasion; decency of conduct; seemliness;
   that which is seemly or suitable.
   [1913 Webster]

         Negligent of the duties and decorums of his station.
                                                  --Hallam.
   [1913 Webster]

         If your master
         Would have a queen his beggar, you must tell him,
         That majesty, to keep decorum, must
         No less beg than a kingdom.              --Shak.

   Syn: {Decorum}, {Dignity}.

   Usage: Decorum, in accordance with its etymology, is that
          which is becoming in outward act or appearance; as,
          the decorum of a public assembly. Dignity springs from
          an inward elevation of soul producing a corresponding
          effect on the manners; as, dignity of personal
          appearance.
          [1913 Webster]
    
from Bouvier's Law Dictionary, Revised 6th Ed (1856)
DECORUM. Proper behaviour; good order.
     2. Decorum is requisite in public places, in order to permit all 
persons to enjoy their rights; for example, decorum is indispensable in 
church, to enable those assembled, to worship. If, therefore, a person were 
to disturb the congregation, it would be lawful to put him out. The same 
might be done in case of a funeral. 1 Mod. 168; 1 Lev. 196 2 Kebl. 124. But 
a request to desist should be first made, unless, indeed," when the 
necessity of the case would render such precaution impossible. In using 
force to restore order and decorum, care must be taken to use no more than 
is necessary; for any excess will render the party using it guilty of an 
assault and battery. Vide Battery.
