The court noted that if GMB had been an integral party to the loan agreement, the respondents should have applied for GMB's joinder on the basis of either financial or proprietary interest, such as joint owners, joint contractors or partners, citing Morgan and another v Salisbury Municipality 1935 AD 167 at 171 and Amalgamated Engineering Union v Minister of Labour 1949 (3) SA 637 AD at 656-57. The court also observed that any variation, amendment or alteration of the loan agreement would have to be in accordance with the provisions of the agreement itself, which would set out the procedure to effect such changes. The court referenced several authorities on the purpose and stringent nature of summary judgment procedure, including Schoeman v New Mark 1919 CPD 55; Maharaj v Barclays National Bank Ltd 1976 (1) 418 (AD); and Breitenbach v Fiat SA (Edms) BPK 1976 (2) SA 226 (T).
