1 U.S. Code § 108 provides "Whenever an Act is repealed, which repealed a former Act, such former Act shall not thereby be revived, unless it shall be expressly so provided." However, many state codes provide rules on construction on both this and in cases where the amendment to a former act is repealed without also amending or repealing the former act itself. This is, as far as I know, not covered by Federal law directly.
In general, I would like to understand, on the Federal level, the rules of construction regarding the repeal of an amendment amending a prior act. Would the original, unamended, text be in effect, or would the amended text still be in effect?
For example, say Law A provides "XYZ", Law B provides "Law A is amended to say 'ABC'", and Law C provides "Law B is repealed." In this instance, after the effect of all three laws, does Law A provide "XYZ" or "ABC"?
To be more specific, I am only interested in this instance in regards to legislative amendments, not constitutional amendments.
