An appeal against an interlocutory ruling shall be admissible only if it is brought
at the same time as the substantive appeal.
However, where the interlocutory ruling orders measures which are illegal or might obstruct
the normal course of justice, it may be appealed against to the Supreme Court before
judgment on the merits under the conditions laid down in section 474.
