Smarthavicharam
Smarthavicharam or Smaartha Vichaaram, was the ritualistic trial of a Nambudiri woman and fellow male adulterers who were accused of illegitimate sexual relations. If the accused women was found guilty, she and the men found involved with her (known as jaaran) were excommunicated or ostracized (Bhrashtu) and banished. The permission of Maharaja (king) was necessary for the conduct of smarthavicharam. The practice is nonexistent today and last reportedly took place in 1918.
