Calcium and bone health : position statement for the Australian and New Zealand Bone and Mineral Society, Osteoporosis Australia and the Endocrine Society of Australia

This position statement was prepared by the Working Group of the Australian and New Zealand Bone and Mineral Society and Osteoporosis Australia. The final statement was endorsed by the Endocrine Society of Australia.

Currently, the balance of evidence remains in favour of fracture prevention from combined calcium and vitamin D supplementation in elderly men and women.

Adequate vitamin D status is essential for active calcium absorption in the gut and for bone development and remodelling.

In adults with a baseline calcium intake of 500–900 mg/day, increasing or supplementing this intake by a further 500–1000 mg/day has a beneficial effect on bone mineral density.

Calcium intake significantly above the recommended level is unlikely to achieve additional benefit for bone health.

Australian property investment advice : an unregulated industry and the need for better consumer protection laws

Currently, consumers have no means of protecting themselves when they are looking for property investment advice in Australia. There is no uniform national or State regulation in the property investment advice and marketeering industry. The only protection and remedies currently available are those under the general consumer protection laws scattered in various Acts, and even so, these have numerous problems. This paper highlights what those problems are under the general consumer protection laws and suggests some changes to the current system. The paper also argues that a national co-operative approach is the only way to move forward in this area and suggests that the constitutional difficulty can be overcome by using the legislative conferral of state powers provision, which has often been overlooked. The paper also argues that a new regulator be set up to administer and enforce the new proposed laws on property investment advice.

Exodus of 'mineral rights' from the South African Mineral Law

Transformation of the mineral law system as part of the new political  dispensation in South Africa has long been foreseen. Subsequent to a Green and White Paper, as policy documents, the Department of Minerals and Energy published a Mineral Development Draft 8il12000 for public comment. This eventually culminated in the acceptance by Parliament of the Minerals and Petroleum Resources Development Act 28 of 2002, which came into operation on 1 May 2004. The Act will transform thE! mineral law system and the mining industry in" general. In this article the phaSing-out by the Act of the historical notion of 'mineral right' is examined. It is argue..d that the Act will lead to an exodus of the notion of mineral rights and will replace It with less secure prospecting rights and mining rights which, albeit real in nature, will depend on compliance with provisions of the Act and the exercise of discre.Von by the Minister.

Mineral law and the doctrine of rights : a microscope of magnification?

The doctrine of rights has become part of private law jurisprudence. In this article the application of the doctrine in two decisions dealing with surface support in mineral law is examined. It is argued that the decision of Kriegler J in Elektrisiteitsvoorsieningskommissie v Fourie, namely, that the right to surface support is an entitlement, is more correct than Anglo Operations Ltd v Sandhurst Estates (Pty) Ltd in which it was decided that the right to surface support is a competence. It is submitted that depending on the legal location of the entitlement in the relationship between owner and miner of land one may simply refer to either an owner's entitlement to surface support or a miner's entitlement to undertake opencast-cast mining.

Mineral rights are dead! Long live mineral rights!

Whilst being mindful of the eventual extinction of the legal notion of mineral rights in South Africa upon expiry of the transitional measures in terms of schedule II of the Mineral and Petroleum Resources Development Act 28 of 2002 on 30 April 2009, the classification of mineral rights by the supreme court of appeal in the Anglo decision is to be welcomed, even though it is somewhat ironic at this stage. (As to the extinction of the notion of mineral rights, see Badenhorst "Mineral rights : 'year zero cometh?'" 2001 Obiter 119; "Exodus of 'mineral rights' from South African mineral law" 2004 Journal of Energy and Natural Resources Law 218.) It will, however, be shown in this discussion that the decision of the supreme court of appeal will extend beyond the statutory transitional period and will also have an impact on rights to minerals or rights to petroleum as created in terms of the Mineral and Petroleum Resources Development Act (hereafter referred to as the act). For purposes of this discussion, one can simply continue to refer to mineral rights that developed from the common law as "mineral rights", whilst referring to the new rights created in terms of the act as "rights to minerals and petroleum". The present decision only deals with coal as "minerals".

"Minerals", "petroleum" and "operations" in the Mineral and Petroleum Resources Development Act 28 of 2002 : a geologist as devil's advocate for a change? "

This article examines the meaning of "minerals", petroleum, "operations" and activities in relation to such substances to determine the ambit of the application of the Minerals and Petroleum Resources Development Act 28 of 2002, the type of rights necessary for such operations and activities and the ambit of these rights. The examination of the meaning of these concepts takes place with reference to prior definitions in statutes and also from a natural science and geology perspective. An attempt is made to show that the legal definitions do no always correspond with the geological meanings and the meanings on the ground. It is questioned whether in recent legislation why more reliance is not placed on input from geologists in the field.
