Questão jurídica principal
Whether the cantonal court arbitrarily refused revision because B.'s recantation was not serious enough to undermine the conviction.
Decisão extraída
The refusal was not arbitrary; the cantonal court could regard the recantation as implausible and insufficient to shake the original findings.
Fundamentação extraída
B. had repeated his incriminating statements four times during the investigation, had no apparent reason to lie against X., and the later notarized retraction came only years after the facts with unconvincing explanations.
