In reply to Ann Teallach: In practice things tend to be a little more complicated. Taking a case to the Court of Session is expensive and Highland Council, like virtually every other, will not do this until everything else has been tried first. Unscrupulous landowners know this which allows them to exploit the situation. Also, as another large landowner with an estate not far from Ledgowan (and who is no fan of their management philosophy)once said to me, being obnoxious is not in itself a crime; the Council's advocate would have to prove to the satisfaction of the court that the behaviour of the estate owner/employees was specifically intended to discourage or prevent access, which is not as easy as it sounds. Given the intrasigence of the estate, I believe it will go to court eventually, it may just take some time.
As for bulldozed tracks, the SNP administration recently decided not to bring hill tracks into the planning system. No great surprise, as it is consistent with their general philosophy that "economic development" - however dubious - trumps all.
