Hi thanks for your question. My name is ***** ***** I can answer this for you.
If the fence is owned by you (i.e. paid for and put up by you), then you can insist that others do not do anything to you fence (including tie things to it) without your consent. Doing so without your permission would be a trespass on your property and you're entitled to ask them to remove it.
If they failed, you could ask the Court for an order requiring them to remove it.
Technically, he might complain about criminal damage.
However, you would say that you asked him to remove them and if he refuses/fails, they you're entitled as a matter of civil law to remove them yourself by cutting them.
The police will probably take little notice, but they could in theory get involved if there is a complain about criminal damage. The CPS would not likely take further action if you can show that you had requested they be removed and that this was the only way to prevent this continued trespass on your property.
You could issue county court proceedings if you wanted to do it all properly, as this is the "safest" route, because if the court says you can remove them, the police/CPS will simply not interfere.
Yes, I think that would be reasonable, subject of course to you being satisfied that cutting them is the only way to remove them.
Are they directed to you or do they incidentally overlook?
Okay, if they are pointed directly at your premises, then you may have a claim you can make to the information commissioner for a breach of date protection principles. There is good guidance on this, which I will look for now for you.
