Questione giuridica chiave
Whether the statutory forms of security under § 99 ZPO are exhaustive and whether a bank guarantee may be ordered instead of cash deposit.
Decisione estratta
The statute exhaustively lists the admissible forms of security; among them, cash deposit, securities deposit, and bank guarantee are equivalent. A bank guarantee from a first-class local bank may be ordered if it provides equivalent security.
Motivazione estratta
§ 99 ZPO lists the types of security exhaustively. The three statutory forms are of equal value. The judge must balance both parties' interests and may not exclude other statutory forms merely because they require more effort to assess.
