29. An appeal also lies, in accordance with article 511, from an interlocutory judgment of the Superior Court or the Court of Québec but, as regards youth matters, only in a matter of adoption:
(1) when it in part decides the issues;
(2) when it orders the doing of anything which cannot be remedied by the final judgment; or
(3) when it unnecessarily delays the trial of the suit.
However, an interlocutory judgment rendered during the trial cannot be appealed immediately and it cannot be put in question except on appeal from the final judgment, unless it disallows an objection to evidence based upon article 308 of this Code or on section 9 of the Charter of human rights and freedoms (chapter C-12), or unless it allows an objection to evidence.
Any judgment is interlocutory which is rendered during the suit before the final judgment.
