Paying the bonus would depend on the future payment structure of the company and whether or not bonuses would be employed. If a future incentive structure was to include bonuses and the company had a reputation for not paying the bonuses the incentive would be unlikely to succeed. Why work hard for a bonus you are unlikely to receive?
If, however, you were likely to never use bonuses again AND there was a legal way out it you might consider not paying the bonuses. While not idea, if paying out the bonuses results in the financial instablity of the company then they have to be revoked. Then fire the person responsible for misleading the company.
