The Germaneness Rule
Clause 7 of rule XVI, called the “germaneness rule,” stands for the simple proposition that an amendment must address the same subject as the matter being amended. The germaneness rule was adopted by the House in 1789 and has remained the same since it was last changed in 1822. The purpose of the rule is to provide for the orderly consideration of amendments to bills and resolutions by requiring a relationship between the amendment and the matter being amended. The existence of this rule is one of the key procedural differences between the House and Senate.
