For as long as this pilot program remains in effect,
submission of a pre-appeal review request may extend the period for filing an
appeal brief until a decision is made on the request or the request is
otherwise dismissed.
請問上面這段是否可翻為下面這樣，有關otherwise這邊要怎麼翻好呢?感謝
只要在這個試驗計畫有效期間，提交訴願先行審議程序請求
得延長提交訴願理由書的期限直到針對該請求作出決定，除非這項請求被撤回。

until （a decision is made on the request）or （therequest is otherwise dismissed.） 這裡應該是指兩種情況

在試驗期間，上訴先行審查之請求提出後，在被受理或駁回之前，可延長交付上訴理由書的期限。
