[Marvel/DC] Are there any laws in the US or abroad regarding the occult?

I was just watching the JLU episode where Grundy is resurrected by a trio of kids and it got me thinking; these are kids that bought a book of spells off the internet that would allow them to get revenge on their bullies. Not only is that dangerous in and of itself, but the spell doesn't even go right and Grundy is resurrected as a mindless, killing machine. 

So, with that example in mind, are there laws in either of the major comic universes restricting or outright banning the use of magic or the procurement of magical items by citizens?

Nope, magic is not regulated by law in either universe.  But both universes have the magical realm as self-regulating.  So if you do some vile and twisted dark magic, expect Doctor Strange or Doctor Fate to show up and stop you.  Some kinds of dark magic will require you to break other laws though - like sacrificing someone is still considered murder, and stealing ancient artifacts is still theft.
