🔥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.

Despite being the most widely used herbicide in Aotearoa NZ, the EPA has never conducted a comprehensive risk assessment of #glyphosate.
