The Arizona Supreme Court is standing by a legal doctrine that leans toward allowing initiative measures to go on the ballot even if there are small errors on petitions that voters sign.

A unanimous opinion Thursday says the justices won't reconsider their long-standing rule of ”substantial compliance.''

That rule requires courts to consider whether allegedly flawed petitions still meet disclosure and form requirements as a whole.

The opinion explains the court's earlier order upholding a judge's ruling allowing Proposition 201 on home warranties to remain on the Nov. 4 ballot.

A homebuilders group tried to keep the initiative off the ballot, arguing among other things that it lacked a title and had an incomplete summary.
