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.
