He claimed that he was denied due process and that his rights as a teacher and unionist were violated.
The Court of Appeal agreed, noting that both his deregistration and termination were carried out without following the proper legal and administrative procedures.
In delivering the ruling, the judges emphasized that every teacher has a right to fair treatment under the law and that disciplinary measures must adhere to the Constitution and the relevant labor laws.
By declaring the TSC’s actions illegal, the court restored Sossion’s professional and union rights, allowing him to continue his work within the education sector.
The ruling is seen as a significant boost for Sossion’s political ambitions within the union.
He had declared his intention to contest for the secretary-general position in KNUT’s April elections, and the court’s decision removes any legal obstacles that might have prevented him from participating.
Supporters of Sossion have welcomed the verdict, calling it a victory for fairness, justice, and union democracy.
Speaking after the ruling, Sossion expressed gratitude to the court for upholding his rights.
He said the judgment reinforced the principle that no teacher or union leader is above the law and that proper procedures must always be followed in matters of discipline.
He also highlighted that the decision strengthens his commitment to fight for the rights of teachers across the country.
Legal experts say the judgment sets an important precedent for how teacher discipline and deregistration cases should be handled in Kenya.
They noted that public institutions, including the TSC, must ensure transparency and fairness when making decisions that affect professionals.
The April elections are expected to be closely watched, with Sossion’s participation now guaranteed.
His supporters believe that his experience as a union leader and his victory in court will enhance his credibility and appeal among teachers.
