Campaigners fighting plans to open a new Tesco Express store in Portishead say they are considering appealing against an alcohol licence granted for the store.
North Somerset Council licensing committee approved an application by the supermarket giant earlier this month to sell alcohol at the new store at West Hill from 6am to 11pm, seven days a week.
The store is due to open shortly in the former Royal Oak pub at West Hill but because all Tesco Express outlets are less than 3,000 sq ft, they do not have to adhere to the main Sunday hours trading restrictions.
Councillors approved the application despite objections from local residents and the Portishead Tesco Action Group (PTAG) who said the trading hours were too long and could lead to anti-social behaviour, litter and parking problems.
Other stores in the area, including Costcutters, are only allowed to sell alcohol between 8am and 10pm.
Campaigners have 21 days from the day of the decision to appeal against the ruling. It costs around £400 to lodge the appeal and then the group would have to employ legal representation.
If the appeal is lost, then PTAG could be forced to pay Tesco's legal costs.
PTAG chairman Paul Dunn said: "We are considering our options and whether we make a challenge to the alcohol licence."
The special hearing would be held where the evidence would be reviewed.
Tesco say the new store would attract an estimated 8,000 a week and that alcohol sales only represented between seven and nine per cent of sales.
The store also operates a Think 25 policy to stop under-age drinking and would only offer a limited range of alcohol with about 120 different lines.
News that an appeal may be lodged comes at the same time as vandals smashed in a door and two windows at the store.
The incident is believed to have happened during the early hours of Thursday.
Police are now looking through CCTV footage from cameras in the area.
Portishead Police Sergeant Jim Robinson said: "We are aware of the incident and it is being investigated.
"We would appeal to anyone with information about the incident to contact us."
No one from Tesco was available for comment.
