A more thorough explanation:

Definition: Judicial stacking is the principle that allows a court to interpret insurance policies to permit stacking, under certain circumstances, when the policies do not specifically provide for stacking but public policy is best served by permitting it. It is also a gerrymandering technique in which a large political or racial group is combined in the same district with a larger opposition group.

• Insurance: If a person has two insurance policies that cover the same claim, they may be able to use both policies to obtain benefits. This is known as judicial stacking.
• Gerrymandering: In a political election, a group of voters who share a common interest or identity may be combined with a larger group of voters who do not share that interest or identity. This is done to dilute the voting power of the smaller group and give an advantage to the larger group.

These examples illustrate how judicial stacking can be used in different contexts. In the case of insurance, it allows individuals to obtain the benefits they need when one policy alone would be inadequate. In the case of gerrymandering, it can be used to manipulate the outcome of an election by combining certain groups of voters in a particular way.
