Key legal question
Whether the Federal Court could hear the appeal against the order for a new medical expertise as a separately appealable interim decision.
Extracted holding
The cantonal decision was an interim decision; no formal recusal ground was raised, and no irreparable harm was shown, so the appeal was inadmissible.
Extracted reasoning
An order for further evidence normally does not cause irreparable harm. The asserted needlessness of a second opinion concerns evidentiary assessment and can be reviewed only with the final merits decision.
