BOSTON (AP) — Two months after a judge declared a mistrial in a corruption case against former Massachusetts Treasurer Tim Cahill, prosecutors and Cahill’s lawyers have not reached an agreement on resolving the case short of another trial.

Cahill was accused of scheming to run $1.5 million in taxpayer-funded lottery ads to boost his faltering 2010 independent gubernatorial campaign. A mistrial was declared Dec. 13 after jurors told a judge they were hopelessly deadlocked.

Cahill’s lawyers and state Attorney General Martha Coakley have acknowledged that they are in “discussions” over how to resolve the case.

A status conference to update Judge Christine Roach on the discussions has been postponed several times.

Cahill attorney Brad Bailey said Wednesday he is still hopeful an agreement can be reached to avoid the need for another trial.
