If for one moment you put aside the sentiments, self interests, rights and wrongs you are still left with a covenant - and unlike a promise, a covenant is drawn up because it is legally binding. Regardless of whether the covenant is beneficial or detrimental to your needs, if you are aware of it then you have a lawful duty to try and ensure it is adhered to, since to ignore it might make you liable. Hence, irrespective of whether you agree or not with what is happening, the process now being undertaken is one of upholding the covenant – to satisfy the law. In effect, the nursery has challenged the validity of the covenant and the subsequent legalities will either uphold it, amend it or remove it.
