Final answer:
The principle that restricts the government to only the powers granted by the electorate is known as limited government, which is fundamental in a constitutional government. The Constitution outlines these limitations and the rule of law ensures that government decisions align with established principles, protecting citizens' rights.
Step-by-step explanation:
The fundamental principle of constitutional government that says the government is only given the ability to do what the electorate (voters) allow it to do is known as limited government. In a constitutional government, the Constitution establishes limits and rules for the government to follow and lists individual rights that cannot be violated. This ensures that the rights of citizens are protected and minorities are shielded from oppression by majorities.
Within a constitutional government, the rule of law is essential, ensuring no one is above the law, not even government officials. This upholds the supremacy of the Constitution and guarantees that those who govern base their decisions on established principles or rules. Constitutionalism, which embodies this concept, balances limited government with the fundamental worth of each individual, emphasizing their right to self-determination as laid out by a bill of rights in the Constitution.
