As Greece struggles to find cash to stay afloat, local authorities say they oppose a government decision to use their reserves for short-term financing.
"The government's decision to seize our reserves not only raises legal and constitutional issues, but also a moral one," said George Papanikolaou, mayor of Glyfada, the third-largest municipality in the metropolitan region of Attica after Athens and Piraeus.
"We have a responsibility to serve our citizens," Papanikolaou said by phone on Monday.
Glyfada has about 16 million euros in cash reserves, he said.
Running out of other options, Greek Prime Minister Alexis Tsipras ordered local governments and central government entities to move their cash balances to the central bank for investment in short-term state debt.
