L'Editoriale di Luglio/Agosto 2021

Ancora una volta tempestividi Vincenzo Favata, IT9IZY Il recentissimo decreto legge che si occupa prevalentemente di rilancio, resilienza e di misure di rafforzamento delle strutture amministrative, contiene uno slittamento significativo del termine perentorio precedentemente fissato per procedere alle modifiche statutarie con le maggioranze non qualificate e ciò, principalmente, per consentire agli Enti del Terzo Settore di apportare ulteriori modifiche agli Statuti a seguito dei controlli da parte degli uffici del RUNTS.
