Continuing with Sanskrit based suggestions (after bahuvrihi) we have dharna (from the Freedictionary):

n. A fast conducted at the door of an offender, especially a debtor, in India as a means of obtaining compliance with a demand for justice, such as payment of a debt.

Etymology: Hindi dharn, from Prakrit dharaa, from Sanskrit dharaam, act of supporting, stay; see dher- in Indo-European roots.

Sounds slightly less dramatic than disrobing to the waist and threatening ritual 切腹 (seppuku) to get one's way in feudal Japan. I wonder if this practice (dharna, not seppuku) still exists ?...
