The Indiana Code refers to the amended Constitution. A clause was removed from that section.
@The following text is a transcription of the Constitution in its original form.
Items that are hyperlinked have since been amended or superseded. (emphasis in the original)
Note: A portion of Article II, section 1 of the Constitution was superseded by the 12th amendment.
*Superseded by section 3 of the 20th amendment.
So the rest of Clause 3, that which wasn't superseded, still applies and the clause numbers are still the same.
Did you actually look at your link? The ENTIRE third clause was replaced. Gone completely.
