I would second Dark here and throw a Question at you all , not contradicting but a simple question .

How is a leatsu inhibiting Gigai dangerous to well being of Sendai no Gotei or even Seireitei

Its just inhibits leatsu of a shingami, then merging with the user's soul stripping her/him of shinigami powers . Also its untraceable due leatsu inhibition (ie Rukia ) . How can that remotely effect well being of SS as compared to Hogyoku . Is that good enough of a reason to banish/exile somone that to a Taicho rank Officer
