HELENA, Mont. -

Some central Montana residents are arguing that the districting commission didn't provide proper public notice before making a final decision.
    
A Helena judge heard arguments in the case Friday that deals with a last-minute decision to adjust the assignment of several state senators to new districts.
    
The redistricting commission meets every 10 years to draw new legislative districts of roughly equal population based on updated census information.
    
The lawsuit argues the senators were assigned to specific districts for political advantage. And it says commissioners made the decision by huddling in a series of small, private meetings without public notice.
    
The state told District Judge Mike Menahan that no quorum of the commission ever met privately as alleged, and that the assignments were made at a public meeting in February.
