The Supreme Court  unanimously decided that states and local governments can't impose excessive fines in order to boost revenue.  It stems from a case  involving an Indiana man arrested on a drug-dealing charge.

Police seized Tyson Timbs' Land Rover, saying it was part of the crime.  The maximum penalty for the offense was $10,000, but the car was worth $42,000.

Timbs argued the seizure was disproportionate and excessive.  Wednesday's ruling sets a precedent that the  Eighth Amendment's ban  on excessive fines does, in fact, apply to states and local municipalities.

That means they'll have a property value limit on what they can seize.

That limit already applies at the federal level.  Advocates of the ruling hope it'll curb the practice of what they feel are excessive seizures.

According to  the American Bar Association , excessive fines and fees "disproportionately harm the millions of Americans who cannot afford to pay them."  The decision  also marked Justice Ruth Bader Ginsburg's first opinion since her recovery from recent lung surgery.  Additional reporting from  Newsy affiliate CNN .
