A scribe left a blank line at the bottom of a column mid-verse, creating an unauthorized parsha pesuchah. The Chasam Sofer rules that while the usual erasure-and-rewrite remedy is unavailable when the break falls between verses (due to a halachic catch-22 involving ma'alin bakodesh), correction is permitted here precisely because the break falls in the middle of a verse — removing an invalid mid-verse break is itself an elevation in sanctity, satisfying even the Rambam's stringent standard.
