Paraphrasing (7th paragraph)
Text
One can also list some negative features. First, the adjudication proceeds in closed sessions with no opportunity for the public to observe. Second, although the Appellate Body has created some space for the filing of amicus curiae briefs, in no instance so far has a panel or the Appellate Body acknowledged taking a brief into account that was submitted independently of a government's submission. Third, the Appellate Body has at times seemed arrogant in the way it treated panel findings. Fourth, although the Appellate Body has been willing to correct some of its own mistakes in subsequent decisions, it has not acknowledged the changes.
The main idea of the paragraph
There are also four negative features: first the jurisdiction takes place in closed sessions, second, the panel or the Appellate Body has not considered any amicus curiae brief that was submitted independently of a government's submission; third, the Appellate Body has sometimes shown contempt for panel findings; and fourth, the Appellate Body has not acknowledged the changes although it has been willing to correct some of its mistakes.
WTO争端解决程序也有四个缺点：第一，判决是在不公开的庭审会上进行；第二，专家小组或上诉受理机构没有考虑过作为非政府机构的法院临时法律顾问提交的陈述；第三，上诉受理机构有时候轻视专家小组的裁决；第四，虽然上诉受理机构愿意纠正以前的一些错误，但对此从未承认过。
句子分析
Second, although the Appellate Body has created some space for the filing of amicus curiae briefs, in no instance so far has a panel or the Appellate Body acknowledged taking a brief into account that was submitted independently of a government's submission.
在此句中
1）“in no instance so far has a panel or the Appellate Body acknowledged taking a brief into account”是主句，因为句子以否定意义的词语“in no instance”开始，所以采用倒装的结构，即主语“a panel or the Appellate Body”放在助动词“has”之后；
2）“although the Appellate Body has created some space for the filing of amicus curiae briefs”是让步状语从句，修饰主句中的谓语动词“has（not）acknowledged”；
3）限制性定语从句“that was submitted independently of a government's submission”修饰名词“brief”。
