When the court deals with social policy decisions,the law it shapes is inescapably political-which iswhy decisions split along ideological lines are soeasily dismissed as unjust.

译文：当法庭作出有关社会政治的裁决时，受其影响的法律也不可避免地带有政治性，这就是为什么在意识形态上存在分歧的裁决会很容易被视为不公而不予理会。

点睛：句子的主干是：the law is inescapablypolitical。when引导时间状语从句;it shapes实际上是省略了that的定语从句，修饰the law;破折号后面是由which引导的定语从句，该定语从句中又包含了由why引导的表语从句;split along ideological lines是过去分词短语作后置定语修饰decisions;表语从句中的谓语是are so easily dismissed。inescapably意为“不可避免地”，ideological意为“意识形态上的”，dismissas意为“因…不予理会”。
