A recent audit of Harlingen Waterworks revealed the water company passed more than two dozen budget amendments without city commission approval.
Those results came to light at a commission meeting Wednesday.
The amendments date back to 2006 and were worth more than $6.5 million.
City commissioners told Waterworks that city charter mandates the city commission approve any budget amendment.
Waterworks maintained their lawyers said they do not need city approval to pass budget amendments.
They said from now on they will seek city approval.
