Answer:
When no candidate wins a majority of the electoral vote and the election is sent to the House of Representatives, as happened in 1824, the 12th Amendment has to be applied.
Step-by-step explanation:
The 12th Amendment establishes that if the election is not defined in the Electoral College, the decision will pass to the House of Representatives, which will elect the president from among the 3 candidates with the most votes in the Electoral College. Voting will be done by states and each state will have one vote.
