@space_monkey,
Thanks. Those links help clarify.
My take on this hasn't changed from my initial post.
Under the Supremacy Clause, found in Article VI, section 2 of the U.S. Constitution, both the Constitution and federal law supersede state laws.
https://www.bonalaw.com/when-does-federal-law-preempt-state-law.html Federal laws are the supreme law of the land and judges in every state are bound by them regardless of conflicting state laws.
The United States Code contains the general and permanent laws of the United States, arranged into 54 broad titles according to subject matter.
https://uscode.house.gov/detailed_guide.xhtml U.S. Code Title 18 Chapter 44 § 921 (a)(3)
The term “firearm” means (A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive; (B) the frame or receiver of any such weapon; (C) any firearm muffler or firearm silencer; or (D) any destructive device. Such term does not include an antique firearm.
https://www.law.cornell.edu/uscode/text/18/921 In the U.S. Code that defines "firearm", there is no mention of air or gas weapons. This point is not open for discussion. The U.S. Code determines the definition.
The IL law makes an attempt to redefine "firearm" to include air or gas weapons:
"Firearm" means any device, by whatever name known, which is designed to expel a projectile or projectiles by the action of an explosion expansion of gas or escape of gas; excluding, however:
(1) any pneumatic gun, spring gun, paint ball gun, or B-B gun which expels a single globular projectile not exceeding .18 inch in diameter or which has a maximum muzzle velocity of less than 700 feet per second;
..."
If the intent is to include airguns as firearms, then this is a clear violation of the Constitution's Supremacy Clause.
Now I'm going to go all English Language Nerdy on you. We all remember the difference from English 101 between a "restrictive clause" and a "nonrestrictive clause", right?
https://www.grammarly.com/blog/relative-pronouns/ A restrictive clause is a part of a sentence that may not be removed without rendering that sentence incomplete, difficult to understand, or with its meaning substantially changed.
A nonrestrictive clause adds information to the sentence, but it is not imperative to include it. Usualy bracketed with commas.
Merriam-Webster Dictionary of English Usage specifies that one use the word "which" to introduce a nonrestrictive clause.
So why am I bringing up something esoteric like the correct usage of "which and that" and restrictive and non-restrictive clauses and correct grammar? IDK. Words matter. Clear grammar matters. Especially when attempting to write laws.
Reading the above IL definition is confusing. Does the compound "which" clause add clarity? Not really. Does it only apply to B-B guns? It kind of appears that way. If the clause in question applies to "any pneumatic gun, spring gun, paint ball gun", then the proper english would have been "expel" instead of "expels". When you refer to a group of things..they expel..they do not expels. A singular thing expels. So the entire "which" nonsense must apply to B-B guns. Nit picking, I know..but words and sentence structure matter.
As part of their oath of office, all public servants swear to uphold and defend the Constitution, right? Do we assume the IL authors intended to follow the Constitution and federal law by excluding "any pneumatic gun, spring gun, paint ball gun"? We kind of have to assume that. No public official would knowingly break their oath, right?
The use of "which", in "which expels a single globular projectile not exceeding .18 inch in diameter or which has a maximum muzzle velocity of less than 700 feet per second;", implies a non-restrictive clause..IE not required to understand the sentence..which implies the operative word in the sentence is "excluding". This is further supported by the IL definition of "Firearm Ammunition"
"Firearm ammunition" means any self-contained cartridge or shotgun shell, by whatever name known, which is designed to be used or adaptable to use in a firearm;"
One would assume that in order to be a firearm, said firearm must use "Firearm Ammunition". Cartridge has a very specific definition. By defining "firearm ammunition" with the terminology "self-contained cartridge", the IL lawmakers expressly excluded airguns from their legislation. Airguns do not use cartridges. Well, the exception is the Brocock Air Cartridge..so the law covers airguns that use that system. The IL redefinition of what constitutes ammunition would also likely run afoul of the Supremacy Clause, as ammunition is defined by Code 18 USC § 921(a)(17).
If the intent of the lawmakers was to preempt the Constitution, then they violated their oath of office. They also wrote crappy legislation that is easy to circumvent.
Here's a pic of the IL work-around..
Make sure you have a BB less than .18 in you pocket..put BB in straw..blow into straw..guaranteed not to exceed 700 fps..done ;-)
CA is bad enough. Sure glad I don't live in IL.
