Can Dishonesty Automatically Justify A Summary Dismissal?

Introduction

Termination of employment contract without notice or payment in lieu of notice under section 9 of the Employment Ordinance (Cap. 57), commonly referred to as "summary dismissal", is a serious disciplinary action. It only applies to cases where an employee has committed very serious misconduct or fails to improve after repeated warnings.

What about dishonesty? Say an employment contract provides that an employee is entitled to reimbursement for certain out-of-pocket family expenses. The employee obtained reimbursement with invoices issued to him that were not in fact his or his family's expenses but for expenses incurred by his friend's son. Can such a dishonest act automatically justify summary dismissal?
