Tuhia tētahi tohutoro mō tēnei wāhanga - I mahi a Barnett hei Hekeretari Matua ki te Tari Taonga mai i te tau 1974 ki te tau 1979, i whiwhi i tētahi tūru ki te kāwanatanga mai i te tau 1977 ki muri, ā, ko ia te ringa matau o Denis Healey i te Kāwanatanga o Callaghan. I tēnei wā i mātakitaki ia i te whakamahinga o te mea e mōhiotia ana ko te Barnett Formula e wehewehea ai te whakapaunga a te iwi i waenganui i Ingarangi, Scotland, Wales, me Ireland ki te Raki. I muri mai ka tawai ia mo te ahua rereke me te kore o te mate i whakawhiwhia ki a ia ma te "whai i tana ake tohutao". Whai muri i te Ture o Scotland 1998 me te whakakorenga, i tohe ia ko te Whakataunga he kino ki Ingarangi me whakarere, kia arotakehia ranei. I whakahuatia e ia tenei tirohanga i te tau 2014 i mua tata o te pooti pooti motuhake o Scotland
