Recently my question Could the Senate confirm a new Supreme Court Justice without holding any hearings? was marked as a duplicate of Why are SCOTUS appointee Senate hearings not mandatory?. The two questions arguably different - mine is about nominating a new justice without a hearing, the other is about refusing a hearing to a justice in order to deny them the nomination. However the answer to the older question contains the following sentence:
Theoretically, the Senate can confirm a nominee without holding any confirmation hearing as the requirement of a hearing is not mentioned in the Appointments Clause.
This does answer my question, however the two questions are not about the same thing. When I pointed this out, a comment pointed out the following:
When a question is closed as 'Duplicate, it says, This question already has an answer here. Thus duplicates are based on answers, not questions. See, Why are some questions marked as duplicate?. "The fundamental goal of closing duplicate questions is to help people find the right answer by getting all of those answers in one place." While the questions are different, it happens that the earlier question answers both that question and this question.
Is this the official policy on Politics.SE? On Travel.SE the policy is that the questions must be the same to be marked as a duplicate: A friendly reminder that duplicates should be the same QUESTION, not different questions with similar answers.
