(a) General rule.--The Director of the Legislative Reference Bureau shall, in printing amendatory statutes, cause to be printed the section or part of the statute only as reenacted. Except as provided in subsection (b) of this section, in the section or part of the law reenacted, the Director shall cause to be printed between brackets, the words, phrases, or provisions of the existing statute, if any, which have been stricken out or eliminated by the adoption of the amendment, and he shall cause to be printed in italics or with underscoring all new words, phrases or provisions, if any, which have been inserted into or added to the statute by the passage of such amendment.

(b) Consolidated Pennsylvania Statutes.--In printing as much of any statute as adds an entire title, part, article, chapter, subchapter or other major subdivision to the Consolidated Pennsylvania Statutes, the Director shall cause such addition to be printed in Roman type without underscoring, and in printing as much of any statute as deletes or repeals an entire title, part, article, chapter, subchapter or other major subdivision of the Consolidated Pennsylvania Statutes, the Director shall not cause to be printed the provisions which have been deleted or repealed unless the deletion or repeal was effected by the use of brackets.
