Fresh revelations before the Environment and Land Court in Nairobi have intensified scrutiny over the authenticity of development permits issued in Nairobi County, after forensic experts concluded that signatures attributed to Geoffrey Mosiria were forged.
The findings were filed in EP PET NO. E012 OF 2025, in which members of the Parklands Residents Association have sued the Nairobi City County Government and several individuals over contested development approvals.
According to a forensic document examination report referenced in court, questioned signatures marked “A1–A2” on documents under the heading Green Nairobi – Environment, Water, Food & Agriculture were analyzed and compared against Mosiria’s known signatures marked “C1–C3” appearing on exhibits “B1–B4”.
The forensic examiner concluded that the questioned signatures and the known signatures were written by different authors.
The report states that the documents were sufficiently clear for examination and that the signatures were adequate for comparison.
The analysis focused on individual handwriting characteristics, including beginning and ending strokes, character formation and design, spacing between letters, and connecting strokes.
To enhance accuracy, the examiner used a Video Spectral Comparator (VSC 6000/HS) to magnify and analyze the signatures.
The assessment also took into account natural variations that may arise due to time, age, illness, writing tools, or evolving handwriting habits.
The final opinion submitted to investigators indicated unequivocally that the disputed signatures were not authored by Mosiria.
The forensic findings are now being cited by petitioners as confirmation of long-standing allegations that a large number of development approval documents emanating from City Hall may have been fraudulently processed or forged. Insiders have previously claimed that many approvals issued within Nairobi County lack lawful authorization, and the court-filed forensic report has amplified those concerns.
The revelations emerge amid ongoing contempt proceedings. Court records show that on 14 October 2025, the court ruled that Mosiria was in contempt of a conservatory order issued on 5 March 2025 and directed him to appear for mitigation and sentencing on 4 November 2025.
In a supporting affidavit filed before the court, Mosiria states that he was unaware of the original proceedings and the conservatory orders issued on 5 March 2025.
He maintains that he was not served with either the conservatory order or the contempt application and that he only learned of the contempt ruling through a WhatsApp message forwarded to him by a friend.
He further states that a WhatsApp extract presented as proof of service does not demonstrate that he personally received the documents.
Mosiria also denies authorizing Patrick Analo Akivaga to file a replying affidavit on his behalf, asserting that he neither swore nor signed the affidavit attributed to him and was not a party to the original petition or interlocutory application.
The petition was filed by Kamalkumar R. Sangahani, Jags Kaur and Teddy Obiero on behalf of the Parklands Residents Association.
They have named the Nairobi City County Government and several individuals, including Mosiria, as respondents and alleged contemnors.
The matter centers on development approvals within Nairobi County. With the forensic findings now formally before the court, the case has broadened beyond an individual dispute to raise wider concerns about the integrity of approval processes within City Hall.
The court is expected to consider Mosiria’s affidavit together with the forensic evidence during the scheduled mitigation and sentencing proceedings.
