The semichah of the elders and the decapitation of the calf are by three; [these are] the words of R’ Shimon. R’ Yehudah, however, says: By five. Chalitzah and refusal are before three. The fourth-year fruit and the maaser sheni whose value is unknown are [judged] by three. [Redemption] of articles of hekdesh is [judged] by three. Assessments of movable objects is by three. R’ Yehudah says: One of them [must be] a Kohen. That of real property is by nine and a Kohen, and likewise for a human being.
