Jack Ong’anya is the Managing Partner at Ong’anya Ombo Advocates LLP. He leads the litigation and dispute resolution/ alternative dispute resolution wing. He has offered tremendous representation that has resulted in earning respect among his peers, juniors, and senior practitioners – at one point a Judge said “Ong’anya always appears in Court and ready to proceed with his matters.”

He has advised and represented clients in various intricate transactions such as cross-border distribution contract disputes, complex insured and broker procurement disputes, shareholders disputes, tax disputes, intellectual property disputes, and real estate disputes, to mention a few.

Notable Transactions

EPZ Tax Refunds: he has advised and represented a company on a tax refund dispute since the Kenya Revenue Authority (KRA). These are refund claims that pre-exist the current iTax KRA System whereby KRA has been dismissing any claim that is not captured in the iTax System. It has previously stated that tax collected must be as per the law and specifically provided for under the law, any other collection is unlawful.

Shareholders Disputes: he is representing shareholders who are embroiled in dispute due to fraud that was caused by a former member of the company. The fraud resulted in frustrating the use or access of various properties in terms of fixed assets and money. The total value touching on the dispute is worth more than KES. 500 million.

Economic Crimes: he has secured a “no case to answer” decision from the Court after a Client he was representing was framed by people at the Nairobi County Government’s offices that the Client had orchestrated a plan that resulted in taking a file concerning a dispute between Nairobi County Government and Proland Limited over payments amounting to KES. 131,210,423.12.

Cybercrimes and Bank Fraud: he successfully represented an accused who was falsely accused of having hacked or accessed various bank accounts at Stanbic Bank (Kenya) and transferred funds to his account at Equity Bank (Kenya) and later to KCB (Kenya).

Economic Crimes and Procurement Disputes: he is currently representing two persons who were wrongly accused of engaging in procurement malpractice that resulted in Kenya Power and Lighting Company (KPLC) making payments for unapproved purposes or projects. The case is touching on values above KES. 300 million.

Pro Bono

Secured Release: he has represented a juvenile (this is before the Children’s Act) to be released upon requesting an alternative dispute resolution mechanism between the complainant and the child offender. The case has since been withdrawn and a consent was signed for purposes of allowing the child offender’s parents to refund any money taken and the phone that was stolen.

Sentence Reduction: he represented a person convicted and handed a death sentence by the High Court. At the Court of Appeal, he successfully argued to have the death sentence to be reduced, which the Court of Appeal agreed with him and revised to a 25-year sentence factoring in the years in remand and time already served.
