Above case looks at reasoning for summary dismissal as applies in the Small Business Dismissal Code.
 We believe that the approach and observations in these two decisions are correct. There are two steps in the process of determining whether this aspect of the Small Business Fair Dismissal Code is satisfied. First, there needs to be a consideration whether, at the time of dismissal, the employer held a belief that the employee’s conduct was sufficiently serious to justify immediate dismissal. Secondly it is necessary to consider whether that belief was based on reasonable grounds. The second element incorporates the concept that the employer has carried out a reasonable investigation into the matter. It is not necessary to determine whether the employer was correct in the belief that it held.
 Acting reasonably does not require a single course of action. Different employers may approach the matter differently and form different conclusions, perhaps giving more benefit of any doubt, but still be acting reasonably. The legislation requires a consideration of whether the particular employer, in determining its course of action in relation to the employee at the time of dismissal, carried out a reasonable investigation, and reached a reasonable conclusion in all the circumstances. Those circumstances include the experience and resources of the small business employer concerned.
