Wisconsin Supreme Court decides abortion case that prompted most expensive judicial election in US history

The Wisconsin Supreme Court's newly elected liberal majority on Wednesday voted to strike down a near-total state abortion ban, voting 4-3 to overturn the stringent, 176-year-old law. 

The decision reflected a deeply partisan split, with all four liberal justices voting to invalidate the 1849 abortion law and the three conservative justices dissenting.

It also crystallized the impact of the state's Supreme Court election earlier this year that raked in millions of dollars in donations, the highest amount in U.S. history for a judicial race. It included involvement from then-Trump ally Elon Musk, former President Barack Obama and others.
