The court decided its two blockbuster cases last week by declaring the right of same-sex couples to marry in all 50 states and upholding a critical part of the health care overhaul.
The three remaining cases raise important questions about a controversial drug that was implicated in botched executions, state efforts to reduce partisan influence in congressional redistricting and costly Environmental Protection Agency limits on the emission of mercury and other toxic pollutants from power plants.
The justices also could add important cases for next term on abortion, affirmative action and the power of unions that represent government workers.
