The High Court has ruled that the Electricity Authority was entitled to replace the Transmission Pricing Methodology (TPM) Guidelines in 2020, despite Manawa Energy's (NZX: MNW) judicial review challenge.

The High Court found that the Authority's decision was within the threshold required for a successful judicial review action.

Manawa Energy has expressed disappointment with the outcome, but stands by their decision to seek judicial review, citing the potential economy-wide repercussions of the changes.

The full judgement will be released to the public later today.
