When a party makes allegations or claims, they have an obligation to provide adequate evidence to support it—this is known as the burden of proof. Typically, it lies with the party that is behind the action; it’ll be the prosecutor in criminal cases, and the plaintiff in civil cases. The burden of proof is made up of two elements. Firstly, there’s the legal burden. This means that a fact must be proved to a specified standard of proof. If this isn’t met, the party making the claim will fail with their attempt. Secondly there’s the evidential burden. This is the duty to bring forward enough evidence to raise an issue for it to be considered by the court or jury. The amount of evidence needed will depend on the case. Beyond reasonable doubt is the highest standard and is used in criminal matters, preponderance of the evidence (or balance of probabilities) is used for civil cases, and clear and convincing evidence is required for specific civil issues, like fraud and child custody.

From time to time, as an employer you’ll come across employment law terms that you need assistance with understanding.

What is burden of proof?

It’s a legal term used to describe a claimant’s responsibility to submit a prima facie (accepted as correct, until proven otherwise) case that their argument, or assertion, is correct.

When it comes to burden of proof, employment law disputes require an employee to prove there are facts from which a tribunal can decide in their favour, in the absence of any contradictory evidence.

For example, with regards to burden of proof,  cases will require a claimant to evidence that the respondent’s decision to dismiss them was unfair.

The same applies to other employment tribunal claims, including discrimination and refusal of a statutory right.

Once a claimant has been able to satisfy the employment tribunal, burden of proof will then shift to the respondent. This means the employer, who’ll have an opportunity to argue that the claim is incorrect.

However, before this can occur the tribunal must be happy the claimant has fulfilled their burden of proof beyond a reasonable doubt.

It’s worth noting the burden of proof may shift back and forth several times during a tribunal.

This is as each party tries to establish their argument, while placing onus on the other to satisfy the court.

The judge must then make a decision on the claim based on the ‘balance of probabilities’.

The different types of burden of proof

There’s no significant difference between ‘onus of proof’ and ‘burden of proof’, however the former is terminology typically used in US law as opposed to the UK.

The concept of burden of proof will apply in all employment law disputes ranging from discrimination to refusal of a statutory right.

In claims for breach of contract burden of proof must also be established, which may be more difficult if there's only an oral agreement.

The burden of proof and the Equality Act 2010

To make this clear, section 136 of the Equality Act 2010 states:

 “If there are facts from which the court could decide, in the absence of any other explanation, that a person (A) contravened the provision concerned, the court must hold that the contravention occurred.”

There’s a useful case law example of how burden of proof works in practice. You can see this in the recent Court of Appeal case of Ayodele v Citylink (2017).

In this case, the claimant failed at the first hurdle in their attempt to claim race discrimination as they could not establish a prima facie case they’ve been treated less favourably due to their race.

As a result, the court had no option other than to dismiss their claim.

FAQs: What is burden of proof

In a discrimination claim, who has to prove what?

Initially, the burden of proof is with the employee. They’re required to present a prima facie case. This means facts from a tribunal that could suggest discrimination occurred. If they’re successful, the burden moves to the employer, who then has to prove on the balance of probabilities that the treatment wasn’t discrimination.

What is an employer’s burden of proof in an unfair dismissal case?

If an employee proves they were unfairly dismissed, the burden falls on the employer, and they must show a potentially fair reason for the dismissal. Employers must also show that they adhered to a fair procedure before terminating the contract.

What standard of proof must employers meet in internal investigations?

During workplace investigations, employers don’t need to prove guilt beyond reasonable doubt. Rather, employers rely on the balance of probabilities standard, meaning they must demonstrate it was more likely than not that the alleged incident happened based on the evidence gathered.

How can employers discharge the burden if the employee makes a case?

To successfully meet the burden, employers should provide comprehensive documentation that justifies their actions. This includes meeting minutes, policy documents, and witness statements.

What happens if employers can’t provide an explanation for their actions?

Where an employee shifts the burden to an employer and they’re unable give an adequate sufficient non-discriminatory explanation, the tribunal may be legally required to find that discrimination occurred.
