Records from the Scandinavian-held lands are much-less well documented by comparison. Udal law formed the basis of the legal system and it is known that the Hebrides were taxed using the Ounceland measure. Althings were open-air governmental assemblies that met in the presence of the "jarl" and the meetings were open to virtually all free men. At these sessions decisions were made, laws passed and complaints adjudicated. Examples include Tingwall and Law Ting Holm in Shetland, Dingwall in Easter Ross, and Tynwald on the Isle of Man.
