Sometimes — some time after Baker, where we said it didn’t even raise a substantial Federal question? When — when — when did the law become this?
MR. OLSON: When — may I answer this in the form of a rhetorical question? When did it become unconstitutional to prohibit interracial marriages? When did it become unconstitutional to assign children to separate schools.

JUSTICE SCALIA: I see. When did that happen? When did that happen?
MR. OLSON: There’s no specific date in time. This is an evolutionary cycle.
