Toxicological analysis after asphyxial suicide with helium and a plastic bag

A 23-year-old man was found on a raised hide in lying position, the head wrapped in a plastic bag connected with a helium gas cylinder by a polypropylene tube. The autopsy did not show any specific findings nor did the routine toxicological analysis reveal significant information regarding the cause of death (BAC 0.9 mg/g, diphenhydramine 0.81 μg/ml in heart serum). For the detection of helium in the lungs, gas samples from both lungs were collected by a method ensuring minimal dilution. Gas analyses were performed using a GC–MS with a split–splitless injector and a headspace syringe. As carrier gas the commonly used helium was replaced by nitrogen. Helium was found in clearly elevated concentrations in gas samples from both lungs. Therefore, suffocation by breathing helium enriched, and thus oxygen deficient atmosphere, can strongly be assumed as the cause of death.

Zum Umfang des Individualrechts jedes Wohnungseigentümers auf Minderung der Rücklagenbeiträge gem § 30 Abs 1 Z 2 WEG 2002

Das Recht auf Minderung der Rücklagenbeitr?ge steht jedem Wohnungseigentümer (oder auch einer Minderheit dieser) mittels au?erstreitigem Antrag auch dann zu, wenn der WE-Verwalter einen bestehenden Mehrheitsbeschluss der Wohnungseigentümer dadurch ignoriert, dass er ihnen davon abweichende, wesentlich h?here Rücklagenbeitr?ge vorschreibt. Zur Parteistellung des WE-Verwalters im wohnrechtlichen Au?erstreitverfahren nach § 52 Abs 2 Z 1, letzter Halbsatz, WEG 2002 idF WRN 2006.     

Erneuerung des Strafverfahrens auch ohne Feststellung einer Verletzung der MRK durch den EGMR

§ 363a StPO kann nicht dahin verstanden werden, die Erneuerung des Strafverfahrens auf Grund einer Konventionsverletzung nur in jenen F?llen zu erm?glichen, in denen eine derartige Verletzung bereits in einem Urteil des EGMR festgestellt wurde. Vielmehr ist jedem, der eine Verletzung der MRK mit einer gewissen Plausibilit?t behauptet, entsprechend Art 13 MRK das Recht auf eine wirksame Beschwerde bei einer nationalen Instanz zuzugestehen. Der durch diese Beschwerde gew?hrleistete Rechtsschutz ist indes nicht schrankenlos, vor allem nicht in zeitlicher Hinsicht. Entsprechend Art 35 Abs 1 MRK gilt eine Beschwerdefrist von sechs Monaten ab der endgültigen innerstaatlichen Entscheidung.

The effectiveness of NGO self‐regulation: theory and evidence from Africa

Non‐governmental organizations (NGOs) play an increasingly important role in public service provision and policy making in sub‐Saharan Africa, stimulating demand for new forms of regulatory oversight. In response, a number of initiatives in NGO self‐regulation have emerged. Using cross‐national data on 20 African countries, the article shows that self‐regulation in Africa falls into three types: national‐level guilds, NGO‐led clubs and voluntary codes of conduct. Each displays significant weaknesses from a regulatory policy perspective. National guilds have a broad scope, but require high administrative oversight capacity on the part of NGOs. Voluntary clubs have stronger standards but typically have much weaker coverage. Voluntary codes are the most common form of self‐regulation, but have the weakest regulatory strength. This article argues that the weakness of current attempts to improve the accountability and regulatory environment of NGOs stems in part from a mismatch between the goals of regulation and the institutional incentives embedded in the structure of most self‐regulatory regimes. The article uses the logic of collective action to illustrate the nature of this mismatch and the tradeoffs between the potential breadth and strength of various forms of NGO self‐regulation using three detailed case studies.

SEX EDUCATION LEFT AT THE THRESHOLD OF THE SCHOOL DOOR: STRICTER REQUIREMENTS FOR PARENTAL OPT‐OUT PROVISIONS

Current state law creates the risk that, if sex education is not provided to a child in public school, no similar instruction will be given to the child. Legislatively enacted opt‐out provisions give parents broad control over their child's education by granting them the option to have their child excused from any sex education requirements within a public school's curriculum. Through public school sex education, professionals provide youth information aimed at protecting them from the dangers of pregnancy and sexually transmitted diseases (STDs). A stricter statutory opt‐out provision should be enacted by state legislatures that only allows parents to excuse their child from sex education after a parent attends a 90‐minute STD prevention course and receives the instructional material used in the school's sex education curriculum. Parents should be provided up‐to‐date information and a structural framework designed by the school to encourage them to discuss with their child the many sexual issues addressed within a school's sex education curriculum.
