IN what way could the tribunes check the power of the elected magistrates?

The tribunes of the plebs had the power to veto decisions made by elected magistrates, which effectively allowed them to check and balance the authority of these officials. By exercising this veto power, tribunes could halt legislation or actions they deemed harmful to the interests of the plebeians. Additionally, tribunes were sacrosanct, meaning that any harm or obstruction against them was punishable, further strengthening their position against the magistrates. This mechanism ensured that the voices and rights of the common people were represented and protected in the Roman political system.
