Respected Mr.Arun Trivedi,
In my humble view anything done bonafidely during course of employment does not necessarily entails penal provisions. Your cousin's past unblemished service record speaks in volume about the dedicated attitude. In all probability the following needs to be considered that whatever necessary ought to have been done by and on behalf of your cousin was done and more particularly there is nothing intentional and whatever tragedy has occured it was covered within the meaning of force majuere (whatever reasonable was expected had been done) considering the nature of duty and probability of unintentional human error the employer cannot pass on the responsibility.
One more important aspect to be considered at this point is that to my mind these packets are insured and whatever damage might have occured (may be on account of human oversight and coupled with the probability of not been able to dedect the contents of the parcel but at no stretch of imagination intentional and contrary to the employment stipulations). Even before imposing the penality the employer ought to have put your cousin under notice.
Last but not least if in case the employer thrusts his loss like this is he willing to share the profits so earned during employment of your cousins last ten years employment. It is a business call - in the fitness of things let the same come on record by way of written communication - so that if the situation warrants the same can be escalated for concluding the episode in a logically sound manner not prejudicial and detrimental to your cousin.
Best regards
Daksh
