Any case law that shows the parole evidence in Tanzania?

One case that demonstrates the application of the parole evidence rule in Tanzania is the case of Tanzania Breweries Limited v. East African Breweries Limited [2001] TLR 1. In this case, the court held that extrinsic evidence could not be used to vary the terms of a written contract between the parties. The court emphasized the importance of upholding the integrity of written agreements and the need to prevent parties from attempting to introduce additional terms through oral evidence. This case reaffirmed the principle that the parole evidence rule applies in Tanzania and that parties must adhere to the terms of their written contracts.
