Thought this deserved it's own thread.
I got a call back this afternoon (got off the phone with her five minutes ago) with a Staff Inspector Levin down at Internal Affairs.
She took the "45 day" dispute to Captain Healy, who is the legal advisor for the PPD, and they sat down to look at the statutes.
According to what she told me over the phone, and she encouraged me to quite her on this - "45 days" refers to "calendar days," and not "business days." The Philadelphia Gun Permit Unit has been incorrectly applying the term "business days" and Captain Healy will be re-instructing them in the coming weeks to begin sticking to the definition as written for "day," which is the 24 hour period between one midnight and the next.
She referred to Title 1's "Rules of Construction" -
§ 1903. Words and phrases.
(a) General rule.--Words and phrases shall be construed according to rules of grammar and according to their common and approved usage; but technical words and phrases and such others as have acquired a peculiar and appropriate meaning or are defined in this part, shall be construed according to such peculiar and appropriate meaning or definition.
PAFOA user "tl 3237" hit the right Title, but 1903 is the more specific statute that seals it. The concept is that, since the word "day" has a commonly accepted use, and nowhere within Title 18 is the word "day" used with any more restrictive modifying language such as "business," then the definition of the word "day" has to be that which is outlined in §1991.
Captain Healy will be going to the Gun Permit Unit to make sure that they begin using this interpretation of the word day from now on.
