🔥Glyphosate = case study of regulatory capture. Symptom of a broader problem. NZ EPA haven't risk assessed glyphosate since the '70s. Rejected ELI's application for risk assessment. @eli-aotearoa.bsky.social sought judicial review. Now off to Court of Appeal. psgrnz.substack.com/p/what-is-ha...
What is happening? Can the Courts Protect us if Principles enshrined in Legislation are Set Aside?
A NZ Judge recently took the NZ EPA at its word: 'no grounds for risk assessment'. So it's OK not to do risk assessment. The judge's decision is being appealed. Thank you ELI.

Breaking: We are appealing the High Court ruling that upheld the NZ EPA’s decision finding no grounds to reassess glyphosate or glyphosate-containing herbicides.
Despite being the most widely used herbicide in Aotearoa NZ, the EPA has never conducted a comprehensive risk assessment of #glyphosate.
