When does a David versus Goliath courtroom battle change the course of national climate policy? According to Positive News, Australia's highest court has ruled against proposals to expand the massive Mount Pleasant coal mine in New South Wales.
Retired teachers Wendy Wales and Tony Lonergan launched the legal challenge after state planners approved the project in 2022, arguing that extending the mine by 22 years and doubling its output contradicted national emission-cutting efforts. The New South Wales Court of Appeal declared the initial approval unlawful in 2025, noting that planners failed to consider downstream climate impacts. Positive News reported that MACH Energy took the case to Australia's High Court, which struck down the appeal on Wednesday, setting a legal precedent for fossil fuel approvals.
In other global developments highlighted by Positive News, this year's Nobel prize winners were announced across science and literature. Karl Deisseroth, Peter Hegemann, and Georg Nagel won the Nobel prize in physiology or medicine for optogenetics, a field that uses light to influence neuronal function and has led to a potential therapy for advanced retinitis pigmentosa. Positive News noted that Francis Halzen won the physics prize for studying 'ghost particles', Henri Kagan and Kenso Soai won for chemistry, and Canadian Anne Carson received the literature prize.
Additionally, Positive News reported that four individuals and organisations received the Right Livelihood Award, often known as the alternative Nobel prize. Recipients included computer scientist Timnit Gebru, Pakistani lawyer Jalila Haider for challenging ethnic, state, and patriarchal persecution as a Hazara, the Rural Women’s Assembly, and the Georgian Young Lawyers’ Association. Furthermore, UN member states unanimously agreed to protect the sovereignty of climate-vulnerable island nations if they are inundated by rising seas, as reported by Positive News. A new UN report also found that countries legislating against ageism increased from 44.5% in 2018 to 57.7% today.
Background
According to Positive News, the Australian legal challenge was brought by retired teachers Wendy Wales and Tony Lonergan against MACH Energy's Mount Pleasant coal mine. In science, optogenetics research combined gene therapy with light-stimulating goggles in a study involving 10 participants to target advanced retinitis pigmentosa. For the alternative Nobel prize, recipients were recognised for challenging authoritarian rule, patriarchal violence, and unchecked AI development. The UN declaration on low-lying island nations echoes a recent ruling by the International Court of Justice, while the WHO reported an increase in national long-term care policies and anti-ageism legislation.
Why it matters
These global legal and scientific developments highlight international shifts in climate accountability, human rights recognition, and healthcare advancements. The recognition of figures such as Pakistani lawyer Jalila Haider for defending her community underscores ongoing struggles against persecution. For ordinary readers, these updates reflect shifting legal standards around fossil fuels, sovereign rights for vulnerable populations, and protections against ageism.
What's next
Positive News reported that the Nobel peace prize will be announced on Friday. MACH Energy accepted the ruling regarding the Australian coal mine, and the newly agreed UN protections establish a framework for low-lying nations facing sea level rise.
