Can minority shareholders in Italy challenge a board decision that bypassed proper meeting notice?

If notice rules in the bylaws were skipped and the decision harms shareholders, minorities can act—timing is key.

First check: is it an S.p.A. or an S.r.l.?

S.p.A.

• 
  

  Challenge the board resolution if it violates law/bylaws and injures shareholder rights (art. 2388 c.c. with rinvio to art. 2377 c.c.). Deadline: 90 days from knowledge/registration.

  
  


• 
  

  Ask for urgent suspension of effects (art. 700 c.p.c.).

  
  


• 
  

  Liability action vs directors if damages (arts. 2393, 2393-bis c.c.).

  
  


• 
  

  Serious irregularities: petition ex art. 2409 c.c.

  
  


• 
  

  Call a meeting if ≥10% (or lower bylaw threshold) (art. 2367 c.c.).

  
  

S.r.l.

• 
  

  Challenge members’ decisions not compliant with law/statute (art. 2479-ter c.c.). Deadline: 90 days (nullità: 3 years or no limit in the cases set by law).

  
  


• 
  

  Directors’ conduct: information/inspection + liability tools (art. 2476 c.c.); 2409 usable where serious irregularities recur.

  
  


• 
  

  Precautionary suspension available where needed (art. 700 c.p.c.).
