Imagine that a Halakhic Decisor (decider?) maintains a certain Halakhic position or Hashkafic belief. [I am assuming that such thing as a Hashkafic Decisor exists.] Anyway, is it imperative that s/he necessarily maintain that this position, wherever possible, would apply throughout the entire framework of Halakhah and Hashkafah, and that there could be no contradictions?
(In Yeshivish, the term used for this is "going leshitaso")
