1. Use cross-references sparingly and carefully.
Too many cross-references can make a provision difficult to read and understand. Include a cross-reference only when it is essential to the meaning of the provision, or limits, or makes an exception to the provision.
2. Make a cross-reference a reader's aid.
If you find it necessary to include a cross-reference, cite the specific section designation. After the section designation, if the surrounding text lacks context, include a brief description of the subject matter, so the reader won't be forced to turn to the provision to see what it's about.
|See the above section.
Note the chapter on umbrellas.
See 45 CFR 103.1
|See 45 CFR 103.1, Use of black umbrellas.|
3. Only cross-reference your (or your parent agency's) regulations.
You may cross-reference the regulations of another Federal agency only if the OFR finds that the reference meets one of the following conditions (1 CFR 21.21):
- The reference is required by court order, statute, Executive order or reorganization plan.
- The reference is to regulations promulgated by a Federal agency with the exclusive legal authority to regulate in a subject matter area, but the referencing Federal agency needs to apply those regulations in its own programs.
- The reference is informational or improves clarity rather than being regulatory.
- The reference is to test methods or consensus standards produced by a Federal agency that have replaced or preempted private or voluntary test methods or consensus standards in a subject matter area.
- The reference is to the department level from a subagency.
If you are permitted to cross-reference another Federal agency's regulations, your agency's regulations may not modify the referenced regulations . If any modifications need to be made, your agency must publish the regulations in full text .
