According to this story in the Tennessean, the Metro Council is renewing its attempts to restrict the legal businesses of taco vendors. Tonight's meeting of the Council will include the second vote on space-related proposals, such as rules to keep taco vendors from setting up shop within 1,500 feet of one another. The Metro Planning Department has already voted against the proposals, which means that the bill would need a supermajority to pass the Council in the final vote, if it gets that far.

Previous articles in the Hispanic Nashville Notebook have followed the history of these proposals from their emergence in November 2005:
