Whether the appeal remained live after the fund issued a rectifying opposition decision under Art. 53(3) LPGA
The appeal had become moot because the challenged opposition decision was annulled and replaced by a rectifying decision granting the requested reopening of entitlement review.
Under Art. 53(3) LPGA the insurer may reconsider a decision before forwarding its response. Since it did so and issued a new opposition decision annulling the original refusal and remanding the matter for further examination, there was no longer a dispute for the court to decide.
