The powers of Congress that are written into the U.S. Constitution are called enumerated powers. The powers are set in the amendment of forth in Article I.
I know for a fact one is Power to Coin Money.
there is also the right to collect taxes, declare war, and regulate interstate and trade.
The five expressed powers of Congress are to collect taxes, borrow money on the credit of the United States, regulate commerce, coin money, and lastly to declare war.
Congress has several expressed powers. Some of these powers are the power to declare war, the power to naturalize citizens and the power to raise an army.
Congressional powers not expressed are implied powers.
In the Constitution, delegated (expressed) powers are powers that are explicitly given to Congress. Implied Powers are powers that are not written in the Constitution, but are implied by the Elastic Clause.
Implied powers have allowed the federal government to levy income taxes, conscript armies, and organize a national postal system.
Implied powers are afforded primarily to the Congress by the Constitution that are necessary to bolster the explicit powers as described in the Constitution. The idea of implicit powers is that it allows for some flexibility in terms of interpreting the Constitution.
The power to declare war
The constitution expressly granted some powers to certain parts of government, while other powers were simply implied. Expressed powers reflect an understanding of the importance of the separation of powers. The constitution makes sure, through expressed powers, that no one entity of government has too much power.
general powers to congress such as a:post office :grocery store :sanitary department police department :etc.
Most of the expressed powers of Congress are found in Article I, Section 8 of the US Constitution. While the powers are clearly stated, custom and usage has changed some of the powers. The last clause of that Article, the so-called elastic clause, is responsible for the modification of the powers of Congress. The clause gives Congress the right to "make all laws necessary and proper." It stretches the power of Congress. But, what do the words necessary and proper mean? The issue became part of the "strict" versus "loose" interpretation of the Constitution. In 1819 the Supreme Court addressed this problem in McCulloch v Maryland. The Court ruled in favor of a loose interpretation. This decision gave the Congress the power to make any laws that were necessary to carry out its expressed powers.
To the framers of the constitution there were two types of powers. Expressed power and implied. The expressed powers are ones that are stated like the power to declare war is given to congress, but to the framers it was clear that they didn't mean to have these powers be the final word so they built in a " fail safe" method to give leeway in what congress can do. They used a clause in Article 1 stating what was " necessary and proper." This means that congress can make laws to carry out the expressed powers. To a strict constructionist this is hazy and they are fearful that the government might take on too many powers and they claim that the constitution limits congress to powers only expressed in the constitution. A loose constructionist feel that congress not only has the power but the responsibility to adapt to changing times by making new laws. The existence of the clause in Article 1 indicates that the Framers knew the government would change and have to take on additional powers or obligations. The Supreme Court brought the concept of implied powers to life by hearing cases like aMcCulloch v Maryland in 1819.
The Constitution's division of powers leaves the President with some exclusive powers as Commander-in-Chief, Congress with certain other exclusive powers, and a sort of "twilight zone" of concurrent powers. Congress also has the power to limit the powers of the President.The Constitution describes the powers of Congress more than those of the president because initially Congress was supposed to rule the country while the president didn't do much.
Congress has 27 expressed powers.One of these expressed powers is the power to regulate commerce. This implies that Congress has the right to determine weights and measures so that people know what they are buying and selling. It implies that Congress can ban some substances from being imported or exported. It implies that Congress can pass laws on materials moved on roads or in post office packages.
