The legal fight between the sons of ailing Orioles owner Peter Angelos is to spill into the courtroom for the first time with a hearing Wednesday in Towson. Brothers John and Louis Angelos are battling over the family stake in the baseball team, their father’s famous law firm and his multi-million-dollar office buildings. The fight has brought forth dueling lawsuits and allegations of power grabs, manipulations, even elder abuse. Hundreds of pages of court documents have pulled back the curtain on one of Baltimore’s most prominent and private families. A Baltimore County Circuit judge has scheduled an initial hearing for Wednesday afternoon.
