Basically what that means is that unless your lease specifically says otherwise you have a right to keep hens on your property.
I thought it meant that a lease or covenant CANNOT prevent you keeping chickens and rabbits for personal consumption?
That what I'd been told, its abit legalsie for me though.
I think Dominic is correct here. The "Notwithstanding" means "despite or "in spite of", so the right to keep hens (or rabbits) has precedence unless of course there is a public health issue which is the usual objection raised to chicken keeping (ie vermin, nuisance or noise usually).
"The term notwithstanding is used as a preposition in drafting contracts to indicate that the substantive provision that follows is to apply in spite of, without regard to, limited by, or prevented from operation by some other provision." ref
http://www.gillhams.com/dictionary/431.cfmI'm not sure what Vecten is quoting here but it would appear that you have a right under civil law which contract law can't take away assuming Vecten's quote is civil law. Probably you'd need a legal opinion as I'm just a layman.
