Achadu David Attah is a Partner at 24 Law Chambers with over two decades of practice centred on energy, power, oil and gas, telecommunications, arbitration, and corporate advisory. His career combines substantial in-house experience at the most senior legal levels in major commercial enterprises with private practice as a cross-sector commercial and arbitration lawyer — giving him both transactional depth and institutional understanding that is rare in the Nigerian market.
In the energy and power sectors, his practice covers the full transaction spectrum: upstream and downstream oil and gas deals, cross-border West African asset acquisitions, crude trading documentation, joint venture structuring, regulatory compliance across the DPR/NUPRC, NMDPB and Customs frameworks, and power privatisation mandates. He negotiated Exchange Agreements with PPMC and reviewed all transaction documents with offshore refineries for a major petroleum trading group. He advised on the multimillion-dollar Joint Venture Agreement and IPP Engineering, Procurement and Construction (EPC) Agreement with Saipem and the Rivers State Government, and structured Power Purchase Agreements, Performance Agreements, and industry documents for the AFAM and Ughelli GENCOs and Port Harcourt DisCo during the privatisation of federal power assets.
His West African cross-border transaction experience includes structuring deals involving refinery acquisitions, crude supply arrangements, oil and gas asset acquisitions upstream and midstream, and joint ventures in Côte d’Ivoire and Equatorial Guinea. He has also advised on offshore and onshore drilling contracts, pipe coating, pipeline fabrication, and physical crude trading arrangements across the sub-region.
In the telecommunications sector, he has handled the regulatory and contractual dimensions of major infrastructure projects — including the Nigeria–Benin SAT 3 undersea cable project, the Lagos–Port Harcourt fibre optic link, the Metropolitan WiMAX Project in Abuja, and a nationwide long-haul fibre optic implementation programme.
As a Fellow of the Chartered Institute of Arbitrators (UK), he brings structured international arbitration expertise to the firm’s dispute resolution practice. He has managed arbitration, mediation, and litigation matters across commercial, shipping, and energy disputes, and has supervised external solicitor engagement on all arbitration and litigation arising from his in-house roles.
His public sector advisory work includes assignments under the UK Department for International Development (DFID) / Adam Smith International: donor mapping for the Office of the Vice President under the GEMS 3 programme; legislative review and position paper preparation for the Equipment Leasing Association of Nigeria (ELAN) under ENABLE 2; and procurement reform advocacy under the Business Environment Reform (BER) programme. He has also advised international NGOs, multilateral-funded projects, and government agencies on governance, compliance, and regulatory reform.
He is a Notary Public of the Supreme Court of Nigeria, and was identified by Legal 500 as one of the 100 most influential and innovative counsel working in Africa in 2015.
