There will be multiple lawsuits along with new Finra arbitration cases when the Department of Labor’s fiduciary rule takes effect April 10 and a much larger surge when it is fully effective January 1, 2018, Public Investors Arbitration Bar Association Executive Vice President and President-Elect Andrew Stoltmann said Tuesday.

On the first day, brokers will have a legal obligation to re-examine retirement investment recommendations he or she made three years ago to find if they are suitable, appropriate and not a breach of a fiduciary duty, the private Chicago attorney said.

Most of the new legal actions will happen in Finra arbitration because they will involve brokers, Stoltmann pointed out.

But filings against Securities and Exchange Commission registered investment advisors and other financial professionals will be made in federal district courts, he added.

According to the DOL’s website, starting April 10 firms and advisors must adhere to the impartial conduct standards, and provide a notice to retirement investors that acknowledges their fiduciary status and describes material conflicts-of-interest standards.

Stoltmann said it is very clear private attorneys will be enforcing the fiduciary rule under the Trump Administration because DOL will have to take its marching orders from an anti-fiduciary White House.
