RCMP have established an illegal "exclusion zone" at 28km on Gidimt'en land and are blocking Wet'suwet'en people, hereditary chiefs, food, medical supplies, and journalists.
Today, a Wet'suwet'en woman was blocked while trying to deliver heart medicine for a Cas Yikh elder.
AFAIK the legal background is that the Wet’suwet’ens have never acknowledged the legitimacy of the Canadian government, but that didn't stop the Canadians from designating them some of their own land and Canadian companies from buying the rights to send pipelines through it and Canadian police from arresting them when they try to prevent it.
