**Broker Liability Case Heads to Ohio Supreme Court**
The Ohio Supreme Court has agreed to review whether Interactive Brokers can be held responsible when a customer claims an online trading platform failed to prevent unauthorized or reckless trading. The court’s acceptance of the appeal sets up a major test of how far brokerage firms must go to protect retail investors from their own mistakes or from fraud.
The dispute began when Ohio investor Nicholas Bitounis sued Interactive Brokers after losing substantial sums in his account. Bitounis alleged the firm’s trading platform allowed rapid, high-risk trades that he claims he did not authorize or fully understand. Interactive Brokers countered that its customer agreement placed all trading decisions and risks on the account holder, and that it had no duty to intervene or halt trades it viewed as legitimate. Lower courts split on whether the brokerage owed any extra duty of care beyond the contract terms.
The Supreme Court will decide if Ohio law imposes a duty on online brokers to monitor accounts for signs of unauthorized activity or unsuitable trading, or if the relationship is strictly governed by the account agreement. The outcome will determine whether brokerage firms can continue to rely on broad liability waivers in their contracts or must build stronger safeguards into their platforms. For everyday investors using low-cost online brokers, the ruling could affect account security standards and the ability to recover losses when something goes wrong.
**Bottom Line:** The court will decide how much responsibility online brokers bear for customer trading activity.
