Just read another thread about an upaid Luas fine resulting in a court summons.
It got me thinking: What powers do the Luas ticket inspectors actually have?
Let's say you haven't a valid ticket and are stopped by an inspector
a) inside the tram, or
b) outside the tram.
Q1. Does he have the power either way to issue you a fine on the spot?
Q2. I commonly see them checking newly alighted passengers. If you are outside of the tram when inspected, can you say you had a ticket and left it on the tram?
After all, you were not found on the tram without a valid ticket, so no evidence you didn't have one, and you're now on a public road, so surely he can't stop you walking off?
Q3. And how does he know you will give him a correct name & address anyway?
He can compel you for ID but has no power to search you. And even if he had your full name, most people wouldn't have proof of address on them.
Q4. If you do not cooperate, such as giving no details or trying to just walk off, can they do a sort of citizen's arrest, similar to what a security guard would do to a shoplifter, and wait for the Gardaí to arrive?
