Probably not. However, a court can rule against the airlines if the airline could have prepared itself to deal with expected problems - for example, if the airline failed to prepare sufficient de-icing equipment.
Nonetheless, passengers are eligible for service and support, such as Drinks, Food, access to phones and the internet and, if required, accomodation. These rules are enacted once a flight of up to 1.500 km suffers a starting delay of at least 2 hours. If the delay reaches 5 hours, the passenger may demand a refund or an alternative mode of transport to return to his starting point."
