City leaders on Tuesday will consider placing a measure to extend an about-to-expire library parcel tax on the June ballot.

Neither Mayor Chuck Reed nor his union opponents liked the way California Attorney General Kamala Harris worded the official description of a polarizing pension reform ballot measure, which on Monday was cleared for signature-gathering to place it on the November ballot.

The Sixth District Appeals Court sided in favor of labor unions Tuesday, ruling that Measure B must change the term “pension reform” to “pension modification,” and also alter the way the ballot question is worded. Unless the city appeals the ruling to the California Supreme Court, the ballot measure is set to go before voters June 5.
