Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effects upported the medical principle of “double effect,” a centuries-old moral principle holding that an action having two effects -- a good one that is intended and a harmful one that is foreseen -- is permissible if the actor intends only the good effect.
译文：尽管裁决认为，宪法没有赋予医生帮助病人自杀的权利，然而最高法庭实际上却认可了医疗界的“双效”原则，这个存在了好几个世纪的道德原则认为，如果某种行为具有双重效果（希望达到的好效果和可以预见得到的坏效果），那么，只要行为实施只是想达到好的效果，这个行为就是可以允许的。
考研英语难句类型：结构复杂，分隔同位语，分裂结构
解释：复杂的长句首先抓主干，Althoughit ruled that…suicide，the Court in effect supported that the medical principle of doubleeffect is permissible if the actor…effect.先看although引导的让步状语从句，ruled后有一个that引导的宾语从句；再看主句，主句中的主句是the Courtsupported that…，supported后也是宾语从句，但要注意，宾语从句中，a centuries-oldmoral principle是主语the medicalprinciple of “double effect” 的同位语，同位语中holding that…是现在分词作定语相当于which holds；破折号之间是插入语，对two effects做进一步的解释说明。最后if引导的条件状语从句是主句中的从句。
