[求譯] 又是法律英文 orz

[yunghao (我不懂法律...)]

a party may not appeal from a judgement or decree in his favor,
for the purpose of obtaining a review of findings he deems erroneous
which are not necessary to support the decree

試譯

基於對其認為有誤的判決獲得再次審查的目的,
當事人不得對有利於他的判決或裁定提出上訴.

以上第三行which後面的文意解釋不出來,
跪求高手解答
（which是連著上面的erroneous,但我不確定which指稱的對象是哪個名詞）

→ polylemma:我猜是指重新審理，事實審而非法律審。
→ polylemma:或可參考觀念 http://ppt.cc/dzqY
→ NaDream:個人覺得還是對應findings 也就是findings有兩個子句修飾
→ polylemma:Review of findings... 才是
推 l10nel:which指findings: the findings are not necessary to
→ l10nel:support the decree, but the party deems the findings
→ l10nel:erroneous.原文後面立刻接了一個很大的But，建議整體一起看
→ l10nel:有助瞭解。這句真的第一字母小寫，最後不加標點？要注意。
