(B) In determining whether a permit holder or an agent or employee of a permit holder has proven the affirmative defense provided by division (A) of this section, the liquor control commission or the trier of fact in a court of record shall consider any written policy that the permit holder has adopted and implemented and that is intended to prevent violations of division (A)(1) or (2) of section 4301.22 and of sections 4301.63 to 4301.636, 4301.69, and 4301.691 of the Revised Code.
