Selling liquor and having a boutique in same premises

I own a bar licensed to sell intoxicating liquors and use the same premises for my boutique. I have been served with a letter by the Municipal Authority requiring me to close down the business of boutique for the reason that it is not allowed to have a boutique in the same premises licenced to intoxicating liquors. Is this the law or just the desire of the Municipal Authority? Please guide me.

It is the law and the Municipal Authority is right. Section 67(1) of the Intoxicating Liquors Act [Cap.77 R.E 2002] prohibits the use of premises licensed for bars for other businesses other than the businesses connected with the hotel e.g. restaurant, selling tobacco etc unless the seller obtains a prior written consent of the Municipal Authority. In the absence of prior written consent from the Municipal Authority, it is illegal to run both a bar and boutique in the same premises.
