Key legal question
Whether the appellant knowingly aided forgery in office by submitting an untrue invoice.
Extracted holding
He could foresee and accept that the invoice would be checked internally and documented, so his conduct amounted to intentional assistance to the officials' forgery in office.
Extracted reasoning
Given his professional role, the transaction's importance, and the amount invoiced, it was not arbitrary to infer he expected a written verification process; the exact form of the verification was an incidental detail irrelevant to aiding intent.
