An order for security for costs is entirely within the court's discretion and is a rule of practice, not substantive law. When exercising discretion to grant security for costs, the court must balance: (1) the legitimate right of a party to access justice and seek redress from the courts; (2) the need to protect the opposing party from financial prejudice where there is demonstrated conduct of instituting multiple proceedings, abandoning them, failing to comply with procedural rules, and not paying costs; and (3) ensuring the amount ordered is not extortionate but reasonable and proportionate to safeguard the successful party's ability to recover costs. A pattern of reckless litigation - including successive applications ruled not urgent, failure to prosecute matters to finality, procedural irregularities, and non-payment of costs - justifies an order for security for costs. However, the amount must consider the financial capacity of the party ordered to pay and must not unduly restrict access to justice.
