The Chelsea captain was found not guilty of racially abusing Anton Ferdinand in a game in October and the former England manager's son suggested they were pleased by the newsJohn Terry's acquittal of the charge of racially abusing QPR's Anton Ferdinand.
Chelsea captain Terry was found not guilty following a week-long trial at Westminster Magistrates' Court in which fellow club and international team-mate Ashley Cole stood as a witness.
And it was welcome news for the former England manager after a disagreement with the FA led to his departure from the role with the national team.
Pierfilippo told The Sun: “We have just seen the news online and we are very happy.
“My personal view, as a lawyer, is that the final answer to this matter came from where it was always supposed to come.”
Capello chose to resign in February following the FA's decision to strip Terry of the England captaincy, which he felt had undermined his authority as team manager.
Despite their stance in February, Terry was permitted by the FA to travel to Poland and Ukraine as part of Roy Hodgson's England squad for Euro 2012, while Anton's brother Rio was omitted.
The FA will now have to decide whether to press on with their own investigation into what happoened during the QPR-Chelsea match, following the conclusion of legal proceedings.
