The owner is obviously entitled to give you reasonable notice to leave without reason but must give you access to attend the horse during that notice.
What exactly do you want to know about this?
Based upon this evidence, (or rather, lack of it) the police cannot prove beyond all reasonable doubt that you cut the cable. Indeed, if you didn’t cut the cable, it will be impossible for them to prove.
If the owner will not let you have access to the horse to remove it, you can refer the matter to the police and although they will probably say it’s a civil matter, they may have a quiet word simply to keep the peace.
If the yard owner will still not let you have the horse back then there is no option but to apply to court for an injunction to make the owner give you access to remove the horse. It might be worthwhile getting a solicitor to write threatening the application to court for an injunction and legal costs.
Can I clarify anything else for you?
if you have a contract with the livery yard, then you are entitled to the notice in the contract. I am assuming that all the costs are paid up to date.
If you don’t have a contract with the livery yard, then the notice must be reasonable and that would probably be 1 month.
Because there is animal welfare at stake here, if they will simply not give you access to tend to the animal and to remove it, you have no option but to make an emergency application to court on Monday for an injunction to make them give you access. You need to get a letter to them telling them exactly that and that if you have to do that, you will be making an application to court not only for the injunction but also for the legal costs involved with it.
You will have to accept you are going to have to make alternative arrangements probably within the next month
When you get a moment please rate the service positive. It doesn’t cost you anything but helped me greatly as I then get paid.
We can still exchange emails.
If they have told other people that you’ve cut the cables, which obviously you haven’t done waste upon what you have told me, then you can threaten a defamation claim if they do not apologise and withdraw the allegations
