Thin on the right so far

Only 4 of the 25 outlets with a published leaning rating that ran this story are rated right.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

Australia's High Court has overturned the approval for MACH Energy's Mount Pleasant coal mine expansion. The court ruled 3-2 that the Independent Planning Commission had failed to consider Scope 3 emissions, which are generated when coal is burned. The expansion would have doubled annual production from 10.5 million tonnes to 21 million tonnes and extended the mine's life by 22 years. The case was brought by the Denman Aberdeen Muswellbrook Scone Healthy Environment Group.

Disagreement on the court's reasoning

The High Court upheld the NSW Court of Appeal's ruling that the Independent Planning Commission had failed to consider the climate impact of Scope 3 emissions. The High Court's summary stated that the commission had failed to consider imposing conditions to minimise greenhouse gas emissions, specifically Scope 3 emissions, as required by law. PerthNow reported that the High Court struck down the appeal on Wednesday morning. The Queenslander digest stated that the High Court cemented a landmark finding for climate change cases.

Omissions

None of the left-rated digests mention the specific figures for the planned doubling of annual production or the extension of the mine's life by 22 years. The right-rated digest does not mention the specific figures for the planned doubling of annual production or the extension of the mine's life by 22 years, nor does it name the environmental group that brought the case.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

14 rated outlets

  • Left-rated reports highlighted the victory for environmentalists and retired teachers, referring to the case as a 'climate win' and a 'battle of the ages'. They noted the 3-2 split decision and the High Court's backing of two retired Muswellbrook teachers against MACH Energy. These reports emphasised that the ruling halts the coal mine expansion and reshapes mine approvals. They also quoted Wendy Wales, president of the Denman Aberdeen Muswellbrook Scone Healthy Environment Group, stating that the ruling acknowledges the risks posed by climate-influencing activities and that the true long-term costs of export coal must be considered. Some reports noted the potential impact on 17 coal proposals in the NSW planning pipeline and the establishment of a legal template for future climate litigation.

It stated that MACH Energy sought to extend the mine's life and double its yearly output. The report mentioned that local residents launched a legal challenge after the state planning commission approved the plans. It detailed the NSW Court of Appeal's unanimous ruling that planning authorities must consider Scope 3 emissions and that the High Court struck down the appeal. The report included a quote from the court's summary regarding the failure to consider conditions to minimise greenhouse gas emissions.

  • The right-rated report stated that community environmentalists have beaten an international mining company in Australia's High Court, cementing a landmark finding for climate change cases. The headline used was identical to that of the centre-rated outlet.

Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 36. The sections above set out what each side emphasised, in its own terms.
Is High Court halts coal mine expansion over emissions left or right?
Neither side dominates it. Of the 25 rated outlets on this story, 56% are rated left, 28% are rated centre, 16% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of High Court halts coal mine expansion over emissions biased?
High Court halts coal mine expansion over emissions is one event reported by 36 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting High Court halts coal mine expansion over emissions?
When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
Which outlets covered High Court halts coal mine expansion over emissions?
36 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What was the High Court's decision regarding the Mount Pleasant coal mine expansion?
The High Court of Australia struck down the approval for MACH Energy's Mount Pleasant coal mine expansion. The court ruled 3-2 that the Independent Planning Commission had failed to consider Scope 3 emissions, which are generated when coal is burned.
What are Scope 3 emissions and why were they important in this case?
Scope 3 emissions are indirect emissions caused when coal is eventually burnt, including when exported overseas. The NSW Court of Appeal ruled that planning authorities are legally required to consider the climate impact of these emissions on local communities, a finding upheld by the High Court.
What would the expansion of the Mount Pleasant coal mine have entailed?
The expansion would have doubled the mine's annual production from 10.5 million tonnes to 21 million tonnes. It also would have extended the mine's operational life by 22 years.
