Where a worker alleges occupational injury, disease, or disability arising from employment, such claims must be brought under the Workers' Compensation Act, and not through human rights enforcement.

FACTS

The Applicant, Musinguzi Oscar, was employed as a technical operator (and supervisor of employees of an independent contractor, Job Connect Limited) at Crown Beverages Limited’s Kakungulu Plant. He was responsible for operating and maintaining the waterline for the processing, bottling, and production of NIVANA water (Jumbo).

The Applicant’s key factual averments were that during his line of work, he was exposed to ozone gas used in processing and bottling NIVANA water, without being provided with any protective gear.

As a pioneer of Jumbo water processing, he initially worked manually, ozone gas was circulated in the product water tank in the same operating room where it was manufactured, causing direct accumulation and exposure.

He worked alone in this condition, as the only technical operator, for approximately one and a half years, suffering continuous chest pain, with minimal remedial action taken by the Respondent (only an additional operator was added).

He is currently receiving treatment from the Lung Institute, treatment intended only to relieve pain and sustain life, not to cure.

On 23 August 2022, he shared his medical report from Doctor’s Hospital via email and WhatsApp with his direct supervisors (HR Mr. Derrick Mboga, Production Manager Mr. Godwin Mwesezi, and Quality Manager Mr. Isaac WhatsApp Guma).

Upon the Respondent realising his deteriorating health, he was allegedly coerced into signing an apology letter for assaulting a fellow worker and was subsequently dismissed from employment.

The Respondent’s plant at Kakungulu allegedly fell short of compliance with conventional production standards, and the company had, at times, to explain the presence of foreign matter in water to consumers.

The Respondent, Crown Beverages Limited, opposed the application through an affidavit sworn by Mugerwa Willy (Quality Compliance Manager), contending that the Applicant was not a direct employee of the Respondent, but a supervisor of employees of an independent contractor (Job Connect Limited).

The use of ozone gas in packaged drinking water is locally and internationally accepted; most packaged water is referred to as “ozonated drinking water.” That the Respondent operates a modern, automated, computerised ozone gas generator with an ozone gas level monitor fitted with sensors to ensure employee safety.

Personal protective equipment (PPE), including respirator cartridges, industrial gloves, ear plugs, safety shoes, and bump caps, is always provided, and safety notices are conspicuously displayed.

The video evidence relied upon by the Applicant depicted an orientation exercise only; no ozone was in use during those sessions, and PPE was not required. The Applicant was lawfully dismissed for assaulting a fellow worker, as evidenced by his own written apology and disciplinary hearing records. Any claim arising from workplace injury or disease is adequately addressed under the Workers Compensation Act and its regulations, not through constitutional enforcement proceedings.

ISSUES FOR DETERMINATION

1. Whether the application was competently before the Honourable Court.

2. What remedies, if any, were available to the parties?

LEGAL REPRESENTATION

Applicant: Musinguzi Oscar, represented by Nyanzi, Kiboneka & Mbabazi Advocates

Respondent: Crown Beverages Limited, represented by Raymond Aruho & Co. Advocates

COURT’S FINDINGS

On the Competency of the Application

The Court examined Articles 50(1) and (2) of the Constitution of the Republic of Uganda and Section 3(1) of the Human Rights (Enforcement) Act, noting that constitutional enforcement jurisdiction is reserved for matters directly relating to fundamental rights and freedoms. The Court observed:

“In order to proceed or bring an action under Article 50 of the Constitution, the matter must relate directly to fundamental rights and freedoms guaranteed under the Constitution.”(Per Ssekaana J. in Kimpi Isabirye v Attorney General and Another, Misc. Cause No. 23 of 2017*)*

The Court found that, despite being styled as a constitutional rights enforcement application under Articles 40(1)(a) and 45 of the Constitution, the substance of the Applicant’s claim was compensation for alleged occupational injury and wrongful dismissal, matters squarely governed by the Workers Compensation Act and its regulations.

On the Misuse of Constitutional Jurisdiction

The Court cited the Privy Council authority in Harrikisson v Attorney General (Trinidad and Tobago) [1980] AC 265, where Lord Diplock emphatically stated:

“The notion that whenever there is a failure by an organ of government or a public authority or public officer to comply with the law, this necessarily entails the contravention of some human right or fundamental freedom guaranteed to individuals by Chapter 1 of the Constitution is fallacious... The right to apply to the High Court under section 6 of the Constitution for redress when any human right or fundamental freedom is or is likely to be contravened is an important safeguard of those rights and freedoms; but its value will be diminished if it is allowed to be misused as a general substitute for the normal procedures for invoking judicial control of administrative action... The mere allegation that a human right or fundamental freedom of the applicant has been or is likely to be contravened is not of itself sufficient... if it is apparent that the allegation is frivolous, vexatious, or an abuse of process... made solely for the purpose of avoiding the necessity of applying the normal way for the appropriate remedy.”

Applying this principle, the Court held that the application was an attempt to circumvent the established procedures under the Workers Compensation Act, a practice courts have consistently condemned as an abuse of court process.

HOLDING

Application dismissed with costs

The Court declined jurisdiction and dismissed the application with costs to the Respondent. Specifically, the Court held that:

1. The application was not, in substance, a matter of enforcement of human rights.

2. The Applicant’s grievances relating to workplace injury and dismissal are adequately and properly addressed under the Workers Compensation Act and its attendant regulations.

3. The attempt to invoke constitutional enforcement jurisdiction to bypass the Workers Compensation regime constituted an abuse of court process.

4. No constitutional violation was established; the application was premised on alleged injury and disease arising from an employer–employee relationship, not a constitutional rights issue per se.

KEY TAKEAWAYS

1. Courts will only entertain constitutional enforcement applications where there is a genuine, direct violation of fundamental rights. Mere relabelling of contractual or statutory employment disputes as constitutional grievances will not suffice to invoke constitutional jurisdiction.

2. The Workers Compensation Act is the Appropriate Remedy

Where a worker alleges occupational injury, disease, or disability arising from employment, the Workers' Compensation Act (Cap. 225) provides the exclusive and adequate statutory framework. Employees and their advocates must channel such claims through the statutory workers’ compensation Act

3. Constitutional Litigation Cannot Substitute Statutory Procedures

Following Harrikisson v Att-Gen (Trinidad & Tobago) [1980] AC 265, a long-standing persuasive authority, the constitutional right of access to court for human rights redress loses its value when deployed as a shortcut to avoid ordinary legal procedures. Such conduct is treated as an abuse of court process.

4. While the court dismissed this application on procedural and jurisdictional grounds, the underlying factual dispute highlights the need for employers to: (i) provide adequate PPE for all workers exposed to industrial gases, including ozone; (ii) comply with occupational health and safety standards; (iii) maintain automated safeguards and monitoring systems; and (iv) document and respond promptly to employee health complaints.

5. Employment Relationships and Independent Contractors

The Respondent’s defence was partly premised on the Applicant being a supervisor of employees of an independent contractor (Job Connect Limited), rather than a direct employee.
