1. A founding affidavit is not fatally defective merely because the date of the deponent's signature differs from the date of the commissioner of oaths' stamp, provided there is sufficient evidence on the face of the document showing proper commissioning by way of stamps and signature of the notary public. 2. While a supporting affidavit referring to a non-existent deponent has no value and should be removed from the record, it does not invalidate the entire application where the founding affidavit itself is properly commissioned. 3. It is undesirable and not in the interest of justice for a legal practitioner to continue representing a party where his actions may result in him being called as a witness, though this alone does not invalidate the application. 4. The High Court, as a court of inherent jurisdiction, may hear co-joined applications for condonation and leave to appeal in the absence of prohibitive law, as rules are made for the court and should serve justice. 5. In applications for condonation, the court must exercise judicial discretion considering the degree of non-compliance, the explanation, prospects of success, importance of the case, and principles of fairness to both sides. 6. For leave to appeal against interlocutory orders, the test is whether the applicant makes out a reasonable arguable case, not whether there are strong prospects of success.
