SAN FRANCISCO -- There are those in the U.S. who tie up the courts with questionable lawsuits. Then there's Patricia Alice McColm.

McColm has filed more than 50 lawsuits and hundreds of police complaints over the past 25 years. She has been described by a San Francisco judge as the "most vexatious, vexatious litigant" the jurist had ever seen. McColm then sued the judge for libel.

But if, in the words of a San Francisco columnist, "time truly wounds all heels," McColm may be headed for a sticky end to her days as resident in a neighborhood she has made a legal battleground for years. A couple of weeks ago the company that holds the mortgage on her house was set to foreclose. McColm allegedly hadn't made a mortgage payment in two years and was almost $90,000 in arrears, but she managed to temporarily stave off foreclosure by filing a bankruptcy brief. Now her house is now up for sale.
