Reply To: Blank line on line 2 when line 25 is blank
The only thing specifically addressed in BF regarding blank lines is lists. However, it IS recommended (and the BANA formats committee is trying to make it part of an errata or update) that if something ends on line 24 or 25 that requires a blank line following it (like the box line you mentioned) that blank line is at the top of the next page.
Regarding lists: 8.3.4a says: Start the list on line 1 when a running head is not used, if there are two or more blank lines at the bottom of the previous page. Start the list on line 2 when braille is on the last or next-to-last line of the previous page.
