The year-end fair at Kovan City in Aljunied GRC came to an abrupt end Wednesday, with its organiser set to appear in court for operating without a licence.
The National Environment Agency (NEA) said last night it had applied for a summons against Events Business Management (EBM) on Monday.
"The operator will be required to attend court in due course," it added in a statement.
Earlier in the day, stunned and confused stallholders, told by EBM to pack up and close shop, swiftly put up "last day sale" signs as they counted their losses.
The fair, with 15 stalls selling merchandise such as bags and clothes, started on Nov 22 and was to have gone on for 70 days until Chinese New Year next year.
But it failed to get a licence as it did not submit a letter of consensus from the neighbourhood merchants' association, as required under Section 35 of the Environmental Public Health Act.
The Act states that no one "shall promote, organise or stage any temporary fair, stage show or other such functions or activity without first obtaining a permit from the director-general".
An NEA spokesman said: "Consequently, the trade fair at Kovan City requires a licence, regardless of how the organiser or operator describes it."
If convicted, EBM can be fined up to $1,000.
The NEA also disclosed it was not the first time EBM had flouted the rule. It was fined in May last year for a similar offence.
