Acharei Rabbim L'Hatot in Halachah

In the Halachic Methodology sphere the Kitzur SA supports the concept of "majority [or consensus] of Posqim"

This is almost explicit in KSA 109:1 re: drawn water used to bake Matzah before 12 hours have passed.

The mention of the minority opinion also suggests that it has been rejected as l'chatchilah Halachah, but may be in the tool bag for cases of b'di'avad and Bish'at Had'chaq.

Summary: Majority of Posqim create normative Halachah

Minority opinions are valid in case of emergency only

Shalom
