Cleveland Browns face obstacles in moving to a new domed stadium, invoking the "Modell Law."

Why it matters: The invocation of the Modell Law by Cleveland Mayor Justin Bibb could potentially halt the Browns' plans to relocate to a proposed domed stadium.

What's new: Mayor Bibb has sent a letter to owners Dee and Jimmy Haslam, citing the Modell Law that requires an agreement with the city or a six-month advance notice before a professional sports team can relocate from a tax-supported stadium.

Yes, but: The Browns have previously filed a federal lawsuit seeking clarification on the application and scope of the Modell Law.

• In response to Bibb's letter, the Browns stated that the statute and the city's actions create uncertainty and do not serve the interest of Greater Cleveland.

What to watch: The outcome of the legal proceedings and negotiations between the Browns and the city of Cleveland will determine the team's future stadium plans.

What's next: The Browns owners, the Haslams, aim to build a $2.4 billion domed stadium and entertainment complex in Brook Park, just south of Cleveland.

• The city has proposed funding half of the renovation costs for the current stadium, which opened in 1999.

The bottom line: The clash between the Browns' desire for a new domed stadium and the invocation of the Modell Law raises questions about the team's future location and the larger issues surrounding regional growth and economic impact.
