You need to know about a rule that protects certain people from getting in trouble when they do their job. This rule applies to Customs officers and anyone who helps them.

If you're a Customs officer or someone helping them, you won't get in trouble for things you do or don't do while using your powers under this law. But there are three important things you need to do:

First, you must act in good faith. This means you're trying to do the right thing.

Second, you need to act in a reasonable way. This means you're not doing anything silly or extreme.

Third, you need to honestly believe that you're allowed to use your powers. You can't just use them whenever you want.

If you do all these things, you won't be held responsible even if something goes wrong.
