What steps do governments need to take on climate change?

On 23rd July the International Court of Justice CJ passed an Advisory Opinion on Obligations of States in respect of Climate Change. 

The opinion has clearly not been issued in isolation. It sits alongside a history of Intergovernmental Panel on Climate Change (IPCC) reports published since 1990, with increasingly urgent scientific evidence. It supports the Paris Agreement 2015 targets to limit warming to 1.5 to 2 degrees Celsius, implying a halving of greenhouse gas emissions by 2030, and net zero emissions by mid-century. Governments are currently in their third round of making Nationally Declared Contributions (NDCs) towards the Paris Agreement. 


Fiduciary duty, ESG and climate change

Fiduciary duty is the obligation of a decision-maker to act in the best interests of their client. Trustees, fund managers, directors – even cabinet ministers – have a fiduciary duty. The whole financial system rests on discharging it appropriately. Should the discharge of fiduciary duty have regard to environment, social and governance (ESG) issues and climate change? And if so, how? 

The value of the informed expert

0o3512 128 128By arboricultural consultant and accredited expert witness Mark Chester of Cedarwood Tree Care.

The role of the expert witness in advising on claims is a key element. Having an informed guide to give counsel on the merits of a case can ensure that wise decisions are taken either to pursue or defend a claim. What may surprise is that arboriculture, my own specialism, is unregulated. During my two decades as an Arboricultural Consultant, I have encountered evidence, sometimes quite limited being given undue merit, as those instructing are unaware of the limitations of the ‘expert’.

When I am instructed to review a case, a starting point is to explore existing evidence and its merit. I have found the term ‘expert’ being applied widely to individuals whose credentials are not thus. In one case, where a tree had broken and cased a road accident, the tree owner strongly defended their situation, and the condition of the tree, based on the opinion of their ‘tree expert’, who suggested inclement weather was the reason for the failure. It was when I explored further and found out the inclement weather was not in that locality, and the ‘expert’ was the individual who mowed the lawns and trimmed the trees, that the claim was recognised as having merit.

Mediation: floodgates, or yet another false dawn?

You may have seen my article last December, and many similar from other mediators, with the title Have the Floodgates Finally Opened? We rejoiced at the case of Churchill v Merthyr Tydfil County Borough Council [2023] EWCA Civ 1416 when, at long last, the Court of Appeal overturned Halsey v Milton Keynes General NHS Trust [2004] EWCA Civ 576 where Dyson LJ had said: “…to oblige truly unwilling parties to refer their disputes to mediation would be to impose an unacceptable obstruction to their right of access to the court.” He said that this would offend Article 6 of the European Convention on Human Rights, which establishes the right to a fair trial. 

Well, now there isn’t an obstruction. Sir Geoffrey Vos, Master of the Rolls, decided that a judge can now insist that the parties go to mediation before being allowed a hearing. So all those years where judges imposed costs orders, made pointed remarks from the bench and kept parties waiting for many months, are over. Yippee! Parties can be helped by a friendly mediator, promptly and at modest cost, and have their own solution to their dispute. Wonderful! 

Forewarned is forearmed: how the virus affects dentistry

A personal perspective on COVID-19 from an expert witness and specialist in restorative dentistry.

We began to hear of the coronavirus pandemic in Wuhan Province in China in early January 2020.

Rather than wait for formal advice from our authorities, I contacted a colleague working in Hong Kong, who was well acquainted with the effects of the SARS outbreak in 2003, a variant of coronavirus. A similar pandemic of MERS that had followed in the Middle East in 2012 led me to contact colleagues in the Emirates. They kindly passed on the protocols that were adopted by them at that time for me to implement immediately in my own clinic.
