“Over the last 15-plus years I have worked at the intersection of governments, international institutions, multinational companies, investors and NGOs to improve corporate conduct and to promote human rights and sustainable development. As Deputy Assistant Secretary, Democracy, Human Rights and Labor at the US Department of State between April 1999 and January 2001, I was instrumental in the State Department/British Foreign Office initiative that forged the [VPs]. While I have not had a formal role with the [VPs] since early 2001, I published a number of articles and case studies focusing on their origins and development, and consulted with several major companies on their implementation over the first five years after their launch. Over the last 10 years, I have provided informal counsel to governments, companies and NGOs involved in the process and continue to follow the process closely. I am currently a member of the boards of several NGOs in the human rights field, including Chair of the Advisory Board of Global Witness.”
“… the [VPs] … is a set of principles designed to guide companies in maintaining the safety and security of their operations within an operating framework that encourages respect for human rights, have been adopted by many mining companies over the years including Xstrata. The principles have the backing of the United Nations.”
“…expert evidence is admissible undersection 3 of the Civil Evidence Act 1972 where the Court accepts that there exists a recognised expertise governed by recognised standards and rules of conduct capable of influencing the Court’s decision on any of the issues which it has to decide and the witness to be called satisfies the Court that that he has a sufficient familiarity with and knowledge of the expertise in question to render his opinion potentially of value in resolving any of those issues. Evidence meeting this test can still be excluded by the Court if the Court takes the view that calling it will not be helpful to the Court in resolving any issue in the case justly. Such evidence will not be helpful where the issue to be decided is one of law or is otherwise one on which the Court is able to come to a fully informed decision without hearing such evidence.”
“It seems to me to be clear that by this passage in his judgment Oliver J. was not confining expert evidence to evidence directed to the rules and practices of “professional institutes”
"Before admitting the opinion of a witness into evidence as expert testimony, the Judge must consider and decide two questions. The first is whether the subject matter of the opinion falls within the class of subjects upon which expert testimony is permissible. This first question may be divided into two parts: (a) whether the subject matter of the opinion is such that a person without instruction or experience in the area of knowledge or human experience would be able to form a sound judgment on the matter without the assistance of witnesses possessing special knowledge or experience in the area and (b) whether the subject matter of the opinion forms part of a body of knowledge or experience which is sufficiently organised or recognised to be accepted as a reliable body of knowledge or experience, a special acquaintance with which of the witness would render his opinion of assistance to the Court. The second question is whether the witness has acquired by study or experience sufficient knowledge of the subject to render his opinion of value in resolving the issue before the Court."
“If and in so far as any evidence that Mr. Warner is able to give could be relevant to the issues that have to be decided in this case, it would appear that it would derive from his knowledge of what, as a matter of fact, other mining companies may or may not do, and what standards they apply, in trying to deal with the problem of people coming on to their land as trespassers, and how they police matters. However that would be purely factual evidence and is not a matter of expertise.”
“There is nothing before the court today in terms of evidence that suggests that a body of recognised opinion exists as to what are the appropriate steps to be taken in terms of policing a mine or dealing with public order issues arising in consequence of people trespassing in or near a mine. Thus there is no objectively ascertainable standard or consensus against which to judge the defendants’ behaviour.”
“An experienced trial judge is well able to determine questions of negligence against the appropriate matrix without the assistance of somebody coming in and saying what they would have done in a similar situation, or expressing a view as to whether what the Defendants actually did was reasonable, in the light of their own experience in similar (or different) situations, which appears to be the high water-mark of what one would be able to get from Mr. White. This is just the sort of evidence that Mance J ruled to be inadmissible in The Ardent. Thus the subject-matter of Mr White’s putative opinion, so far as it is possible to discern anything about it, does not appear to be something on which expert evidence is permissible.”
