Before Their Lordships:

  • M.B. Dongban-Mensem JCA
  • Paul Adamu Galinje JCA
  • Ibrahim M. Musa Saulawa JCA

Parties:

Appellants:

  • Tyonex Nig. Ltd
  • Ebamic Pharmacy Ltd.

Respondent:

  • Pfizer Ltd.
Suit number: CA/L/25/08Delivered on: 2011-03-21

Background

This case involved a dispute between Tyonex Nig. Ltd. and Pfizer Ltd. regarding the infringement of a patent (No. RP 9970) relating to the pharmaceutical product branded as AMLOVAS. Tyonex and Ebamic Pharmacy Ltd., acting on behalf of all who import, sell, or use AMLOVAS, sought declaratory and injunctive reliefs to affirm the validity of the patent and to restrain Pfizer from further dealings with the product. In response, Pfizer denied the infringement and counterclaimed for damages arising from actions taken by Tyonex that allegedly harmed their business operations.

Issues

The principal issue presented was whether the trial court's decision to deny Tyonex their right to cross-examine Pfizer’s witness, who provided an affidavit instead of appearing in person, violated Tyonex's right to a fair hearing.

Ratio Decidendi

The Court of Appeal found that the need for cross-examination is fundamental to ensuring a fair legal process. By granting an affidavit in the absence of the witness and without affording Tyonex the opportunity to challenge that evidence, the trial court compromised the fairness required in legal proceedings. The Appellate Court emphasized that oral evidence must be direct, as stated in Section 77 of the Evidence Act.

Court Findings

The trial court had erred in its handling of the case by allowing affidavit evidence without providing Tyonex with the right to cross-examine. The Court of Appeal reiterated that:

  1. Fair hearing includes equal treatment and opportunity for both parties to present their case.
  2. Cross-examination serves to weaken, qualify, or destroy the case of the opponent and to ensure justice is not only done but seen to be done.
  3. Without cross-examination, there can be no reliable assessment of the witness's credit or the truth of their testimony, rendering judicial pronouncements susceptible to bias.

Conclusion

Ultimately, the Court of Appeal set aside the decision of the trial court, ruling that the denial of cross-examination fundamentally flawed the legal process and violated Tyonex's right to a fair hearing. An order of costs was awarded to Tyonex, affirming their legal standing following what the court characterized as a miscarriage of justice.

Significance

This case underscores the importance of the right to cross-examination in judicial proceedings, reinforcing that affording parties a fair opportunity to challenge evidence is fundamental to achieving justice. The ruling serves as an essential precedent emphasizing that no valid judicial decision can stem from a flawed procedure, particularly those affecting fundamental rights.
