Just out of curiosity I'm looking for examples of laws that require you to do something that puts you in conflict of another law.
This question was sparked by something that happened to my neighbour recently. He found an injured deer in his garden, and trapped it in his shed whilst he tried to find someone to help. A few phone calls later and he found that 1) trapping a wild animal without a license is illegal, and 2) releasing a non-indigenous animal into the wild is also illegal.
So, if he keeps the animal he's breaking the law, and if he releases it he's also breaking the law. I suspect that if he killed and ate it he'd probably also be guilty of 'butchery in an unlicensed premises' or something similar.
Are they any similar examples of mutually exclusive laws?
Update - the deer was a muntjac deer, apparently these are not indigenous (despite being in the UK for over 100 years). According to Wikipedia they are on the list of 'Invasive Alien Species' and cannot be 'intentionally released into the environment'.
I'm not suggesting that there was any realistic likelihood of anyone prosecuting my neighbour, I'm just using this as an example of seemingly mutually exclusive laws.
