9 A further affidavit sworn by Ms Stonham on 2 October 2001 was relied upon to support her joinder as a respondent to the substantive proceedings. I think it unnecessary to refer in any detail to what Ms Stonham therein deposed. She was not cross-examined on the affidavit and it dealt, albeit in outline only, with the commencement of her employment with the Speaker on 12 September 1994 as an Electorate Officer Grade 1 in Ms Harrison's electorate office in Parramatta and subject to Ms Harrison's direction and control in the performance of the work, including as to hours worked and the nature and range of duties performed. I note that much of that affidavit was the subject of objection by both Mr Ellicott and Mr Menzies but, again for present purposes in considering this interlocutory application, I find it unnecessary to consider further those objections. Suffice it to say that the affidavit, together with that sworn by Ms Stonham on 19 September 2001, were directed to supporting the grounds contained in the amended summons, and as relevant to the question of Ms Harrison's joinder as a respondent party to the proceedings.

It seems to me only appropriate in considering the present motion for the joinder of Ms Harrison to attend to the allegations made by Ms Stonham as to whether they arguably fall within s 106 of the Industrial Relations Act. I have outlined earlier the claims made and the grounds in support thereof and, in my view, it is plain that they do so fall. As the Full Court of the former Industrial Court said in Nagle (t/as W D & J L Nagle & Sons) v Tilburg [1993] 51 IR 8 at pp 10-11 :
As a general proposition, we think that all issues arising should be dealt with in the substantive proceedings unless the basis for a challenge, either on jurisdictional grounds, as here, or for lack of a reasonable cause of action, be clearly demonstrated ...
