The ex-Barca chief has voiced his dismay with the decision to ban the Blaugrana from signing players and feels they don't deserve such harsh treatment
World football's governing body announced last week that the Blaugrana are banned from signing players for the next two transfer periods (summer 2014 and January 2015) for breaches relating to the international transfer and registration of players under the age of 18.
The Liga giants have since stated that they will appeal Fifa's ruling and Laporta - who was Barca president between 2003 and 2010 - has little doubt they will eventually be acquitted.
"Fifa has been overly harsh on Barcelona in my opinion," Laporta told reporters.
"They will see that we have been doing things the right way when we appeal, though."
Barcelona are in danger of missing out on completing the signings of Alen Halilovic and Marc-Andre ter Stegen, with whom they have already agreed terms, if their ban is upheld.
