The Israeli rabbinical authorities have felt they had no option but to punish the father for his son's refusal to engage in divorce proceedings.  Israeli wives need their husband's approval to dissolve a marriage. 

The courts use sanctions against husband's living in Israel to compel them to complete their divorce such as freezing bank accounts and cancelling driving licences.  However, this is the first time they have used sanctions against the husband's father in this way.

Having had experience of dealing with assets in Israel, such cases can be complicated in terms of resolving the parties' divorce and financial matters. Obviously the courts are taking steps to try to improve this system within the existing religious rules.
