but from what I gather we, the pro-access lobby, are after is a change in law. Which comes from the legislative arm of government. Similar to the process I believe to be happening in the Welsh Assembly.
I didn't think anyone was seeking (at this stage) a change in the law. The law as it is currently written is not clear on whether or not it covers caving. It isn't specifically excluded but it also isn't explicitly obvious that it is included either. The purpose of this exercise I believe was to seek the learned opinion of a QC on whether they believed that the law (as it currently exists) allows access for cavers or does not.
Clearly Dinah has concluded that the existing law likely covers caving. DEFRA's legal department doesn't share the same view point. We do not know how carefully considered their opinion was and it is therefore possible that their opinion may change when presented with reasonable argument. It may also not change and even if it did change there is no reason why a landowner could not argue that the law still didn't cover caving. It would be ultimately for a judge to interpret the existing law, considering the arguments put to him and existing precedents.
I expect that the next step would be to use Dinah's opinion to attempt to change the official position that the various agencies involved currently hold. If that were successful then I expect it would be unlikely that a landowner would take a differing view.
My own view is that whilst I can see both positives and negatives for more open access, those issues are irrelevant. The law already exists. It either covers caving or it doesn't. If it does cover caving then it is not for those disadvantaged by that fact to stop people exercising their existing lawful rights. It would be for them to campaign to change the law to exclude caving. On the other hand, if it does exclude caving then it is for the proponents of open access to campaign for a change in the law and for the opponents to campaign for the status quo.
