Recent Supreme Court Matters

  • Represented the Children’s Defense Fund, Fair Elections Legal Network, and the Union for Reform Judaism et al. in an amicus brief in Evenwel v.

  • Represented respondent in Kerry v. Din (2015), raising the issues of (1) whether a U.S. citizen’s constitutional rights are implicated by the denial of a visa to her spouse to allow them to live together in the U.S.; and (2) if the U.S. citizen has standing to sue, what is the scope of review and level of information required to sustain the denial.  
  • Represented The Leadership Conference on Civil and Human Rights in an amicus brief in Schuette v. Coalition to Defend Affirmative Action (2014), involving an equal protection challenge to a Michigan ballot initiative (known as “Proposal 2”), which amended the state constitution to prohibit affirmative action in education.  Thirty-one advocacy organizations joined as signatories to Sidley’s brief.

Two prior cases were also dismissed on the pleadings and affirmed on appeal, Depriest v. AstraZeneca Pharms. L.P., (Ark. 2009), Prohias v. AstraZeneca Pharm., L.P., (Fla. Dist. Ct. App. 2007). In another case, summary judgment was granted and class certification was denied. Weiss v. AstraZeneca Pharm. (Cal. Ct. App. 2010).
