Does anyone know the legalities behind this, the law literature online for the UK suggests to me that they are illegal, as its blocking a public right of way (public parks cannot be fenced off)
"Public Parks" and "Public rights of way" are not the same things.
The public are allowed "Formal ( or De Facto )" access to public parks and "Legal" access to rights of way.
Also access can be blocked if there is a safety issue.....plus it keeps the Pikies out !
And more importantly if its the council then ( as they are a law unto themselves ) they can do what they like regardless.
