lögrétt (ON) noun

An enclosure for livestock gathered together following the summer grazing season. Landowners were required to drive all animals found on their land to these enclosures so that they could be sorted and collected by their owners through identification of lawful ownership marks (ON lögmark). Locations for lawful enclosures were determined by the men of the district (ON heraðsmaðr, see hæraþsmaþer), or possibly men of the commune (ON hreppsmaðr).
