Many terms of the tenancy agreement in the present case may be used as illustrations. If, for example, the landlord had sought to rely on cl 2(g), which required the tenant to keep the interior of the premises, including the sanitary and water apparatus, furniture, doors and windows, in good and tenantable repair and condition, the landlord would have needed to identify the particular part of the premises or item said not to have been kept in that condition. The landlord should also explain, by evidence, what the condition was at the start, what the condition was at the end, why the difference amounted to breach rather than fair wear and tear or ordinary deterioration, and what loss resulted. Another example is cl 2(q), which prohibited the tenant from removing items, furniture or fittings except with prior written permission. If the landlord had wanted to rely on this clause, it would have needed to identify the item removed, establish that the item belonged to the landlord, show that it was present and within the scope of the tenancy, prove that prior written permission was not given, and prove the value or loss claimed.
