(Bloomberg) — Trading in Grupo Elektra shares remained stalled Friday as the company called on regulators to maintain a long-standing ban on transactions, saying its lifting would cause “irreparable” damage.

Bids were more than 15% below the previous stock price, exceeding the circuit breaker that triggers automatic halts. A spokesman for the exchange declined to comment.

Bolsa Mexicana de Valores had imposed the trading ban in July after its billionaire owner Ricardo Salinas Pliego accused a creditor of stock fraud. Regulators ordered the exchange to lift the suspension this Friday, even though Elektra said it had won a court order keeping the ban in place. The regulators are yet to be informed of that ruling, the stock exchange said Friday.

“The measure, in addition to violating the rule of law, will generate irreparable damage to the company, generating instability and distortion in the markets, causing conditions contrary to the healthy uses and practices of the market and putting all investors at risk,” Elektra said in a statement.

The back-and-forth is the latest in a long saga related to Elektra, which comprises the bulk of Salinas’ nearly $11 billion fortune that makes him Mexico’s third richest man, according to data compiled by Bloomberg.

The suspension was lifted briefly on Oct. 22, but no trading occurred to “avoid transactions that don’t conform to market practices,” the exchange said in a statement on Oct. 23.

Elektra was cut in August from the country’s benchmark index, setting it up for a steep drop when trading resumes given that a large number of funds that track the index owned the shares.
