Are The Line Item Vetoes Legal?

Here is an interesting post that discusses the issue, with links to conflicting opinions from the Legislative Counsel and the Department of Finance.
ps. Here is an editorial from the Los Angeles Times on the same subject; here is an article from the same paper; here is an article from the San Francisco Chronicle and here is an article from the Sacramento Bee. None of the articles really add much, although one indicates that legislators may file briefs if someone else initiates litigation.
