At my previous employment we had copy of Redgrave’s which we would refer to when we provided advice but despite sleeping with it, it didn’t make me a lawyer.
Since everybody else had decided to join in I have thought why not. Let’s pretend I know what I am talking about!
So the facts as we have been told:
A company had dug up a pavement or footpath ( and we are assuming that this is a public right of way) but once the works had been finished the final remediation of the path didn’t take place “due to lack of labour”. So the spoil was left by the side of the path or on the path(not clear where). It was secured by barriers of the sort described in chapter 8 of the Traffic Signs Manual. Note that these are not designed to completely secure an area but to segregate hazardous areas.
Then” A member of public has than injured themselves on our work materials that was stored enclosed with chapter 8's.”
Not clear how the person injured themselves: did walk into the pile of soil which on a path, did they take a short cut over the pile, was it dark and they did not see the pile?
We are then told “…that a neighbour had moved the chapter 8's to make it convenient for them getting into their property. “
You could argue that being able to get onto your own property is not a matter of convenience but a right , which case it would mean that the following statement could be challenged: ”Am I right in saying that the neighbour has unlawfully removed these…”.
As to what laws this neighbour has broken, I don’t think that anybody on has come up with anything that demonstrates that.
“Also could someone point me in the direction of where to find this legislation where you cannot move these or just it just come under criminal damage?”
To establish criminal a damage or even a breach of section 8 would probably be difficult, as someone would have to prove beyond a reasonable doubt, that this person did what you are alleging they have done. Usually criminal charge are brought not by the individual but the CPS. I am not convinced that they or the Police would be that interested in this matter.
RIDDOR is just about reporting incidents that have happened in workplaces under your controls; it I snot an admission of liability
Anyway I am not a lawyer, but this is my opinion for free.
