Maintaining The Validity Of Guarantees
In Bank of Scotland Plc v (1) Constantine Makris (2)
Ben O'Sullivan (2009) (Ch D), the Court considered the
validity of a guarantee in light of a variation to the underlying
facility agreement between the bank and the borrower company in the
form of a reduction in the amount of the facility.
Bank of Scotland Plc (the "Bank") sought to recover a
sum due under a guarantee provided in relation to a facility
agreement between the Bank and the borrower company after the
borrower company entered into creditors' voluntary
liquidation.
Background
The borrower company was the vehicle for a joint business
venture between three men, Mr Constantine Makris, Mr Ben
O'Sullivan and Mr Vincenzo Spano. The facility agreement
initially provided for an overdraft facility for the company of up
to £250,000. The advance of the overdraft facility was
conditional on the provision of security as follows:
1 A fixed and floating charge, and a legal charge over the
borrower company's leasehold interest in its premises.
2 A guarantee by Mr Spano in the sum of £250,000 supported
by a legal charge over his home (the "Property").
3 An unsecured guarantee limited to £50,000 from Mr Makris
and Mr O'Sullivan expressed to be joint and several.
The facility agreement was signed on behalf of the company by Mr
Spano and Mr Makris. The guarantee for £50,000 was duly
signed by Mr Makris and Mr O'Sullivan.
A complication arose in respect of Mr Spano's guarantee. The
Bank discovered that Mr Spano was not the sole owner of the
Property. It was in fact registered in the joint names of him and
his mother. Although Mr Spano's mother joined with her son in
executing the guarantee and charge in favour of the Bank, the Bank
regarded the security as weakened by the mother's involvement.
As a result, the Bank was only prepared to advance an overdraft
facility to the company of up to £230,000. A revised facility
agreement for this amount was issued by the Bank and the facility
agreement was signed on behalf of the company, as before, by Mr
Spano and Mr Makris. These two defendants subsequently disputed
their liability to meet the guarantee, on separate grounds, and a
dispute arose in respect of whether the guarantee was valid.
Variation of principal contract
Mr Makris argued that the reduction of the overdraft facility
from £250,000 to £230,000 was a material variation of
the principal contract (between the Bank and the borrower company)
and thus discharged the guarantee.
