Questão jurídica principal
Whether an actuarial expert report must be ordered to challenge the fund's premium increase.
Decisão extraída
No. In the absence of concrete grievances against the increase, the court does not order an actuarial expertise.
Fundamentação extraída
A mere general objection to the premium increase is insufficient; the request for expert evidence requires specific, substantiated criticisms of the fund's calculation or basis for the increase.
