They are probably not causing a trespass and in most case of trespass it is a civil offence not a criminal one.
Trespass in most cases starts as a civil matter. But at the point you're asked to leave
and you're preventing the owner from conducting lawful business, it becomes aggravated trespass, which is a criminal offence.
It is worth pointing out at this point that you can use reasonable force to remove somebody undertaking civil trespass, as well as criminal trespass.
There is no law preventing a bus driver from removing somebody from their bus. Despite the misinformation in this thread.
Trespass in law is not what you may think it is.
It's exactly what I think it is. I've been in court proceedings over trespass. I have an expert trespass legal firm's contact details in my wallet for protests I attend.
It relates to interference with land, personal property and physical interference with a person, none of which apply here.
They do apply.
The common law only applies to a property owner or occupier and is very restrictive.
It's not as restrictive as you think.
The bus is not owned (or occupied in the legal sense) by the driver in London.
The driver is operating on behalf of the owner.
I suggest you forget everything about common law - for you and me common law will be just a myth.
Common law is a myth? I'm not sure if this is an incredible level of ignorance or sheer determination to make a point you know to be untrue. Common law is law. Statute law is law.
Written law always replaces common law, which today is almost everything.
It actually doesn't, hence various claims to superior courts in the UK and Europe regarding the authority of statute law, but even if it did, there is no law prohibiting a bus driver from removing a passenger, so this is a moot point.
Common law only applies where written law does not exist and therefore in very specialised situations, which you are very unlikely to meet.
Except the literal situation we're talking about.
In none of this has a breach of the current law occurred.
Nobody says it has

But you're trying to tell people that you disbelief in common law existing prevents bus drivers removing passengers. It doesn't. Common law actually
supports it. It's been ruled on multiple times.
Wheelchair users via the driver can request to share the bus floor space, but the driver can take a quick look and determine whether even asking is realistic or just a waste of time and possibly offensive.
The law allows the driver to just drive off.
Yes, and this is something I believe politicians should change via statute law.
If the wheelchair user is or becomes abusive as a result then the wheelchair user becomes liable for action against them and the bus company has every right to exclude them from there buses.
Yes, although public order offences do have a man on the Clapham omnibus test applied to them. If a wheelchair user is denied access to a bus where space exists for all the current bus occupants and the wheelchair user in the wheelchair space, a few shouty words will not constitute a public order offence. In fact most people would probably see them as quite justified. As for civil action, good luck! Paulley v FirstGroup shows the bus companies much more likely to lose out if they took civil action. And Paulley has a solid track record including just 2 months ago being awarded thousands of pounds in damages.
Kindness and pleasantness gets far more positive results than anger and abuse.
Beware of self-centeredness.
Indeed it does. However when a bus driver doesn't even
try and encourage somebody to vacate a wheelchair space in order for a wheelchair user to board, I think it's pretty understandable that said wheelchair user becomes irate, don't you?
