When state silence becomes persecution: The case of domestic violence refugees in minister for immigration and multicultural affairs v Khawar

In Minister for Immigration and Multicultural Affairs v Khawar, the Federal Court upheld a finding setting aside the refusal of the Refugee Review Tribunal (RRT) to grant a protection visa to a Pakistani woman - Tribunal's failure to consider the notion that state tolerance of violence for discriminatory reasons could amount to persecution under the definition of 'refugee' in the Convention Relating to the Status of Refugees.

Dendritic cells rapidly undergo apoptosis in vitro following culture with activated CD4(+) V alpha 24 natural killer T cells expressing CD40L

Human V alpha 24 natural killer T (V alpha 24NKT) cells are activated by -glycosylceramide-pulsed dendritic cells (DCs) in a CDld-dependent and T-cell receptor-mediated manner. There are two major subpopulations of V alpha 24NKT cells, CD4(-) CD8(-) V alpha 24NKT and CD4(+) V alpha 24NKT cells. We have recently shown that activated CD4(-) CD8 V alpha 24NKT cells have cytotoxic activity against DCs, but knowledge of the molecules responsible for cytotoxicity of V alpha 24NKT cells is currently limited. We aimed to investigate whether CD4(+) V alpha 24NKT cells also have cytotoxic activity against DCs and to determine the mechanisms underlying any observed cytotoxic activity. We demonstrated that activated CD4(+) V alpha 24NKT cells [CD40 ligand (CD40L) -positive] have cytotoxic activity against DCs (strongly CD40-positive), but not against monocytes (weakly CD40-positive) or phytohaemagglutinin blast T cells (CD40-negative), and that apoptosis of DCs significantly contributes to the observed cytotoxicity. The apoptosis of DCs following culture with activated CD4(+) V alpha 24NKT cells, but not with resting CD4(+) V alpha 24NKT cells (CD40L-negative), was partially inhibited by anti-CD40L mAb, Direct ligation of CD40 on the DCs by the anti-CD40 antibody also induced apoptosis of DCs. Our results suggest that CD40-CD40L interaction plays an important role in the induction of apoptosis of DCs following culture with activated CD4+ Va24NKT cells. The apoptosis of DCs from normal donors. triggered by the CD40-CD40L interaction, may contribute to the homeostatic regulation of the normal human immune system, preventing the interminable activation of activated CD4(+) V alpha 24NKT cells by virtue of apoptosis of DCs.

TRAIL expression by activated human CD4(+)V alpha 24NKT cells induces in vitro and in vivo apoptosis of human acute myeloid leukema cells

Human V alpha 24NKT cells are activated by alpha -galactosylceramide (alpha -GalCer)-pulsed dendritic cells in a CD1d-dependent and a T-cell receptor-mediated manner. Here, we demonstrate that CD4(+)V alpha 24NKT cells derived from a patient with acute myeloid leukemia (AML) M4 are phenotypically similar to those of healthy donors and, in common with those derived from healthy donors, express tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) when the cells are activated by alpha -GalCer-pulsed dendritic cells but not prior to activation. We also show that myeloid that human activated CD4(+)V alpha 24NKT cells induced apoptosis of human leukemia cells in vivo. This is the first evidence that activated V alpha 24NKT cells express TRAIL and that TRAIL causes apoptosis of monocytic leukemia cells from patients with AML M4 in vitro and in vivo. Adoptive immune therapy with activated V alpha 24NKT cells, or other strategies to increase activated V alpha 24NKT cells in vivo, may be of benefit to patients with AML M4.

Germline BRCA1 promoter deletions in UK and Australian familial breast cancer patients: Identification of a novel deletion consistent with BRCA1 :psi VBRCA1 recombination

Inherited susceptibility to breast cancer results from germline mutations in one of a number of genes including BRCA1. A significant number of BRCA1-linked familial breast cancer patients, however, have no detectable BRCA1 mutation. This could be due in part to the inability of commonly used mutation-detection techniques to identify mutations outside the BRCA1 coding region. This paper addresses the hypothesis that non coding region mutations, specifically in the BRCA1 promoter, account for some of these cases. We describe a new and detailed restriction map of the 5' region of the BRCA1 gene including the nearby NBR2, psiBRCA1, and NBR1 genes and the isolation of a number of new informative hybridization probes suitable for Southern analysis. Using this information we screened DNA from lymphoblastoid cell-lines made from 114 UK familial breast cancer patients and detected one large deletion in the 5' region of BRCA1. We show that the breakpoints for this deletion are in BRCA1 intron 2 and between NBR2 and exon 2 of psiBRCA1, raising the possibility that this deletion arose via a novel mechanism involving BRCA1:psiBRCA1 recombination. We have also screened 60 familial breast cancer patients from the Australian population, using an amplification refractory mutation system (ARMS) technique described previously by our group, and found one patient with a genotype consistent with a BRCA1 promoter deletion. These findings indicate that germline BRCA1 promoter deletions are a rare and yet significant mutation event and that they could arise via a novel genetic mechanism. Hum Mutat 19:435-442, 2002.

McCabe v Goliath: The case against British American tobacco Australia Services Ltd

Significance of the decision in McCabe v British American Tobacco Australia Services Ltd - ramifications for the possibilities for success of future litigation of this nature in Australia and overseas - ethical and public policy issues regarding the duties of lawyers to the courts and to their clients - whilst a lawyer's implication in the destruction of documents to prevent a fair trial ultimately involves stricter duties, it exposes a need for vigilance against the possibilities for corporations to act outside the public interest, if not the justice system.

Ali v Hartley Poynton Limited

The decision in Ali v Hartley Poynton Limited has significant implications for the stockbroking industry and investment advisors - likely to encourage brokers to adopt a more cautious understanding of their obligations to clients - illustrates the ability and willingness of small investors to challenge the quality of service being provided by their stockbroker.

Australian Broadcasting Corporation v Lenah Game Meats Pty Ltd

Principle issues considered in Australian Broadcasting Corporation v Lenah Game Meats Pty Ltd - whether it was necessary to show a cause of action for an interlocutory injunction to be granted - whether a right to privacy existed - whether the ABC was protected in this case by an implied constitutional freedom - majority rejected a wide interpretation on grounds upon which an interlocutory injunction could be granted - recognition of the possibility of a tort of invasion of privacy under Australian law by five of the six judges.

Parenthood and pay in Australia and the UK: evidence from workplace surveys

This article addresses the effect of parenthood on pay, examining potential reasons for-differences between Australia and the UK that are evident in spite of their similarly minimalist. male, breadwinner style approaches to work/family issues, Although cross-national differences reflect complex intersections of policy combinations, institutional frameworks, patterns of employment and gender contracts that cannot be assessed in a single analysis, the data used in this analysis uncover some of the factors that contribute to different outcomes. Motherhood penalties in the UK appear to be associated primarily with the comparatively low level of part-time earnings in that country, while higher premiums to fatherhood at least in part reflect a wider overall wage distribution. These findings reinforce the heed to interpret earnings effects of parenthood within the context of national patterns of employment and wage distribution; and highlight the breadth of strategies needed to deliver more equitable outcomes.
