The Supreme Court's 5 most contentious cases and how experts think they'll rule

Onlookers who expected fireworks at the Supreme Court over President Trump's travel ban are unlikely to be disappointed by the other battles set to begin Monday as the high court begins its new term.

The Supreme Court's term is loaded with blockbuster challenges featuring questions about political gerrymandering, clashes of free expression and anti-discrimination law, the limits of governmental surveillance, Gov. Chris Christie's battle with America's top sports leagues over betting, and a voting rights case that could affect future elections. The cases provide ample opportunity for decisions to turn on a single justice's vote and for the court to write big or narrow decisions. And in the case of a government surveillance case, how they could decide is a complete mystery.

Here are five cases expected to be among the most contentious and how experts think the justices will rule:

Political gerrymandering: Gill v. Whitford

The Supreme Court in its first week will look to answer if it has any role in determining the constitutionality of political gerrymandering and whether the court should develop a new standard about how to resolve those disputes.

Gill v. Whitford involves gerrymandering questions in Wisconsin, where the challengers hope the high court will adopt their proposed standard for resolving political gerrymandering claims. The standard would rely on demonstrating that redistricting maps were drawn with a partisan motivation, fostered a large and lasting partisan effect, and appeared unjustified by other factors used to draw districts after the census every 10 years.
