I have spoken a couple of times to I am Always Liable regarding my fight with PERS. I am still getting letters from them demanding payment. I have found CA government code section 20160. I recieved my payment in August of 1999 and did not receive a letter from them until 02-26-01 regarding the error. It stands to reason that the amount was figured in July 1999 sometime, therefore wouldn't the six months rule apply. Also, in the copy of the Precedential Decision you gave me it mentions estoppel, could you explain to me what estoppel means. I'm not sure how that Decision applies to me and I am trying to figure out all of it. Thank you very much and I apologize for bothering you again. My original post was in March of this year.
