where are the legislative branch powers derived from
Separation of powers In the United States Constitution, Article 1 Section I gives Congress only those "legislative powers herein granted" and proceeds to list those permissible actions in Article I Section 8, while Section 9 lists actions that are prohibited for Congress. The vesting clause in Article II places no limits on the Executive branch, simply stating that, "The Executive Power shall be vested in a President of the United States of America."[33] The Supreme Court holds "The judicial Power" according to Article III, and it established the implication of Judicial review in Marbury v. Madison under the Marshall court.[34]
