Congressional districts must have nearly the same number of residents. This can't be exact because districts are reapportioned after the census every ten years.
Supreme Court decision in Wesberry v. Sanders
The Legislature doesn't interpret the statute. The Court does.
Wesberry v. Sanders was settled by the Supreme Court in 1964. It didn't outlaw Gerrymandering, it instituted the "one person, one vote" rule which forces all congressional districts have nearly the same population. Gerrymandering hasn't been outlawed.

US Supreme Court decision of 1964 dealing with apportionment of Congressional districts. After a suit against Georgia's apportionment statute was dismissed by the federal circuit court, the case was appealed to the Supreme Court. The Court ruled that all Congressional districts must be equal in size of voting population. The Georgia statute was declared invalid because its unequal apportionment gave greater voting power to residents of certain districts. source: <a href="http://encyclopedia.farlex.com/Westberry+v.+Sanders">Wesberry v.
