Identification of shed or plucked origin of Indian peafowl (Pavo cristatus) tail feathers: preliminary findings

Indian Peafowl (Pavo cristatus) tail covert feathers were studied to investigate the difference between shed and plucked feathers in the context of wildlife offence cases involving the killing of the Indian national bird for the purpose of plucking feathers. Plucked feathers were distinguished from shed feathers by examining their roots under low magnification of a stereoscopic microscope. A chemical test to show the presence of blood on the roots of plucked feathers was used to corroborate the plucked origin of feathers.     

Imperium in Imperio and the Political Origins of the American Labor Conspiracy Doctrine

Many political essayists and judges writing in the early republic sought to circumscribe actions deemed oppressive and otherwise interfering with civil liberty. Associations seeking to advance a set of narrow interests at the expense of the public posed a threat to civil liberty. The way that threat was interpreted in the specific case of labor associations is the subject of this article. It was not the economic power of such entities that gave rise to indictments. Rather the political significance of "private confederacies" acting as an "imperium in imperio" was cited as the key threat to the new political order. Thus, Judge Levy in granting legitimacy to the American labor conspiracy laws did not cite common law precedent but his concern that "a new legislature consisting of journeymen shoemakers" would usurp the legitimate power "of our state legislatures."     

Supreme Court Ruling Creates More Standing Room in the Already Heated Global Greenhouse Gas Movement

This article reviews the recent April 2, 2007 Supreme Court decision in the Massachusetts v. EPA, a highly important case regarding greenhouse gases. The case centered on the Court's review of EPA's denial of a petition to regulate greenhouse gas emissions from new motor vehicles. The Court required EPA to reconsider its denial. The Court found that. 1) the petitioners have standing to challenge EPA's denial of their petition; 2) the Court has the authority to review the denial of the petition; and 3) the Clean Air Act authorizes EPA to regulate greenhouse gas emissions from new motor vehicles. This article looks specifically at the Court's analysis of standing and jurisdiction by Justice Stevens, who wrote the Court's majority opinion, and two dissenting opinions by Justices Roberts and Scalia. Most interesting is how the closely divided Justices (5 to 4 decision) viewed, very differently, the issues regarding standing, the evidence that emissions from new motor vehicles are causing global warming and harm to Massachusetts, and the agency's judgment in denying the petition. Lastly, the article speculates on the impact of the decision and the current activities taking place at the state and regulated community level involving future regulation, litigation, and opportunities by various companies and coalitions to reduce greenhouse gas emissions. The article then presents five broad areas where companies that emit greenhouse gases should need to maintain or increase awareness to better position themselves in the global greenhouse gas movement.     

U.S. Supreme Court Affirms Potentially Responsible Parties' Right of Action for Cost Recovery

In the wake of the Supreme Court's decision in Aviall—that potentially responsible parties (PRPs) are not permitted to seek contribution from other PRPs under CERCLA unless they have been sued or otherwise settled their CERCLA liability—PRPs and the courts have struggled to identify a remedy for those that voluntarily undertake cleanup of contaminated sites. The Atlantic Research decision resolves a conflict among the circuits and clarifies that PRPs voluntarily incurring cleanup costs pursuant to CERCLA, can maintain an action for cost recovery against other PRPs. The authors discuss the current legal landscape regarding actions for cost recovery as presented in Atlantic Research.     

Developmental Validation of the Quantifiler® Duo DNA Quantification Kit for Simultaneous Quantification of Total Human and Human Male DNA and Detection of PCR Inhibitors in Biological Samples*

Abstract: The Quantifiler^® Duo DNA Quantification kit enables simultaneous quantification of human DNA and human male DNA as well as detection of inhibitors of PCR in a single real-time PCR well. Pooled human male genomic DNA is used to generate standard curves for both human (ribonuclease P RNA component H1) and human male (sex determining region Y) specific targets. A shift in the cycle threshold (C_T) values for the internal positive control monitors the presence of PCR inhibitors in a sample. The assay is human specific and exhibits a high dynamic range from 0.023 to 50 ng/μL. In addition, the multiplex assay can detect as little as 25 pg/μL of human male DNA in the presence of a 1000-fold excess of human female DNA. The multiplex assay provides assessment of the DNA extract and guidance for the selection of the appropriate AmpFℓSTR^® Amplification Kit to obtain interpretable short tandem repeat profiles.
