同意你说的应该以直译为主。

第一段：

“first trial judgement”总觉得有点怪怪的。可以考虑以下译法：
Recently, a decision was made by Jianghan District Court on the defamation case of ....

“a.k.a. Fang Zhou-zi”似乎应该出现在方的名字第一次出现的时候比较好。

“truth”似应为“facts”。

“pay attention to”似乎不如“be concerned about”。

“in which”似乎不好。整个句子变成了“court intervened ... in a lawsuit”，建议用“where”或“by which”。

原文中“司法机构介入学术造假”本身有歧义。如果是“司法机构介入学术打假”就更好。整句话可以参考以下译法：

Many Chinese intellectuals all over the world have peen concerned about this lawsuit, where a court actually intervened the exposure of academic misconducts.

“who is supposed to be protected by law.”感觉还是没有译出“本应该受到保护而其实反成了受害者”的意思，时态也不太对。可以参考以下译法：

who should have been protected by the law （注意这里一定要有the）
或
who became a victim of the law by which he was supposed to be protected.

第二段：

“used his pen-name to publish”感觉着重点不太对。建议改为“published ... with pen-name ...”。

“after ... just announced”应该为“just after ... announced”

“candidates’ names”应该注意那个单引号不能用中文的。感觉上用“list of candidates”比较好。

“exaggerating”感觉不够强。建议用“forging”。

中文中的“等”在正式文件中不是“etc”的意思，而是表示列举完了。可以略过不译。

最后一句的“because”用的奇怪。建议去掉。比如：

Fang lost the legal battle at the first trial, and the court ordered...

最后一点：如果要称方为Dr. Fang，则前后最好一致，且对肖也应称Dr. Xiao。人好歹也号称是个ＭＤ。
