Found it. Took a while but here is the section of delaware Code that applies I believe. This is a copy and paste from the Delaware Code:
*********************
Section 6. Amend §1442, Title 11 of the Delaware Code by adding thereto a new paragraph at the end of the section to read as follows:
“It shall be a defense that the defendant has been issued an otherwise valid license to carry a concealed deadly weapon pursuant to terms of § 1441 of this title, where (1) the license has expired, (2) the person had applied for renewal of said license within the allotted time frame prior to expiration of the license, and (3) the offense is alleged to have occurred while the application for renewal of said license was pending before the Court.”.
Approved June 29, 2010
****************
A word to the wise. I would keep a copy of the submitted notorized renewal application and maybe a copy of this section of the Delaware Code on me while waiting for renewal. It could be a real handy this if you get questioned by the Police. Some times the police don't know all the laws.
