Key legal question
Whether an insurer's order to appoint an expert, or refusal to do so, causes irreparable harm and is therefore appealable immediately.
Extracted holding
Such an order does not, by itself, cause irreparable harm and is not immediately appealable.
Extracted reasoning
Under the applicable procedural rules, an incidental decision is only appealable if it is capable of causing irreparable harm. A mere order for expertise, or a refusal to order expertise, does not meet that threshold.
