WASHINGTON – The Supreme Court completes its term Thursday with major decisions expected on partisan gerrymandering and the Trump administration's plan to add a citizenship question to the 2020 census.

The term's premier cases were left hanging until the last day following the court's issuance of 19 other rulings over the past 10 days, including those on religious memorials, scandalous trademarks, racial discrimination in jury selection and the reach of the Freedom of Information Act.

Also up for grabs Thursday: Oklahoma's authority over former Indian territory and a Wisconsin law authorizing blood draws from unconscious motorists.

The justices entered June with more than 30 cases still to be decided, but with most of the attention focused on the ones still pending.

In the census case, the court must decide whether the Commerce Department acted properly in deciding to ask about citizenship on all census questionnaires for the first time in 70 years. Challengers in several lower courts have alleged hidden motives: to depress the headcount of noncitizens in predominantly Democratic states and cities.

The dispute has been complicated by late-breaking evidence challengers say points to partisan and racial motives, denied by the Justice Department. As a result, the Supreme Court's action in a New York case may not end the battle, as a Maryland case still threatens timely printing of census questionnaires.

In two gerrymandering cases, the court must decide whether congressional district maps drawn by North Carolina Republicans and Maryland Democrats are so one-sided as to be unconstitutional. The justices have never before struck down partisan gerrymanders, and their decisions could have an impact in Ohio, Michigan, Wisconsin and other states.

Based on the assignment of majority opinions to date, it appears that Chief Justice John Roberts and, possibly, Associate Justice Samuel Alito will be writing the census and gerrymandering decisions.

The court likely will issue final orders for the term on Friday, including whether to hear President Donald Trump's effort to eliminate the DACA program that provides protection from deportation for undocumented immigrants brought to the U.S. as children.
