The first step is to apply to the registrar to amend the register on the grounds that this has happened maliciously. This is the section you should quote
70Removal of data from register
Data in a registration may be removed from the register—
when the registration is no longer effective; or
on the registration of a financing change statement discharging or partially discharging the registration; or
if the Registrar is satisfied that the data is frivolous or vexatious.
The Registrar must, before he or she makes a decision under subsection (1)(c), give the secured party notice to show cause, within 10 working days of the date on which the notice is given, why the data is not frivolous or vexatious.
If the secured party fails within 10 working days of the date on which the notice is given to show cause to the Registrar’s satisfaction why the data is not frivolous or vexatious, the Registrar may, in the Registrar’s discretion, remove the data from the register.
If data is removed from the register under subsection (1)(c), the court may, on the application of the secured party, make an order directing that the data be restored to the register if it is satisfied that the data is neither frivolous nor vexatious.
The court may make any other orders that it thinks proper for the purpose of giving effect to an order under subsection (4).
The Registrar must restore the data to the register in accordance with a court order made under subsection (4) as soon as reasonably practicable after receiving the order.
