13 Senior counsel for the council submitted that, at the very least, notice should be given to the mortgagee so that it could elect whether to make an application to be joined or to be heard. It was pointed out that in Fibre-Tek the mortgagee had received notice of the proceedings, as is apparent from the above quotation from the judgment. It was submitted that it is impossible for anyone in this Court to know what the mortgagee's attitude might be and that, for example, the mortgagee may well wish to be heard or seek leave to be heard in relation to the question whether, as a matter of discretion, relief should be granted. I was also referred by senior counsel for the council to News Limited v Australian Rugby Football League Ltd (1996) 139 ALR 193 at 297 to 300. That case is distinguishable so far as concerns the circumstances and nature and identity of parties to be joined. However, the Full Court of the Federal Court said at 298:
There are some classes of case where the ascertainment of the necessary parties who ' ought to have been joined ' is not difficult. Where the orders sought establish or recognise a proprietary or security interest in land, chattels or a monetary fund, all persons who have or claim an interest in the subject matter are necessary parties. This is because an order in favour of the claimant will, to a corresponding extent, be detrimental to all others who have or claim an interest. Grosvenor v Permanent Trustee Co of NSW Ltd (1966) 40 ALJR 329 is an example of this class of case.
