The Des Moines school board on Tuesday voted not to waste money and its own attorney’s time on challenging a new state law that requires school board elections to be held only in odd-numbered years beginning in 2009.

It’s a good decision, because the legal challenge almost certainly would have failed.

The board voted earlier this month to implement the new law by shortening the terms of Jon Narcisse and Patty Link by one year. Instead of facing re-election in 2010, three years after they were first elected, they will face voters in 2009.

Although Narcisse has criticized that plan, it’s a lot better than an idea floated earlier in the spring, which would have shortened his term by a year while allowing Link to serve until 2011 before facing re-election.
