The conservative legal challenge to President Barack Obama's executive action on immigration, in line for U.S. Supreme Court review, would force the justices to wrestle with their own conflicting votes on when states have a legal right to sue the federal government.
What's the meaning of "wrestle with one's own conflicting votes on something"? I know 'wrestle with' means struggle with or handle something, but I'm not sure what one's own conflicting votes means. Does it mean that the justices have contrasting views on the issue?
