The decision is here. SCOTUSblog analysis here. Here's the first paragraph of that analysis:
The Supreme Court handed a partial but significant victory to cities today, holding that the Fair Housing Act allows the city of Miami to bring a lawsuit alleging that two banks, Bank of America and Wells Fargo, violated the law when they issued riskier but more costly mortgages to minority customers than they had offered to white borrowers. But it was hardly a complete win for the city, as the court also ruled that the lower court should have applied a tougher test to determine whether the city can recover compensation for its losses. This means that the case will now return to the lower court for it to decide whether there is enough of a connection between the banks’ lending practices and the city’s economic injuries to hold the banks liable.
