What limits has the supreme court placed on gerrymandering

When the boundaries of an electoral constituency are manipulated so as to give advantage to one party of class it is known as Gerrymandering.

"Packing" which means localizing the opposing party's voting power in one district to enervate their voting power in other districts and "cracking" which refers to the art of weakening the voting power of the opposing party's supporters across many districts are two major methods used in gerrymandering.

Explanation:

One example of a gerrymandered US district would be North Carolina's 12th congressional district. Between 2003 and 2016 North Carolina's 12 congressional district was packed. The district has heavily dominated by African-American democrats.

It is the position of the US Supreme Court that redistricting which discriminates on racial or ethnic grounds lacks constitutional backing. However, it has been slow to issue a similarly-strong ruling for partisan redistricting. It is the decision of the Court that unrestrained partisan gerrymandering is unconstitutional.

Answer: The Federal government Authority judges has never been to correct partisan of redrawing electoral district to get electoral advantage. the Supreme Court is used to judging based on a 5-to-4 decision, which allows politicians to only draw electoral districts that brought about their power, unless there are laws preventing them from doing so, which might be congress/state laws.

The conservative majority decision overruled lower courts and also refused two constitutional challenges to partisan district chats.
