One better-paid colleague is now enough to shift the burden of proof in a German equal pay claim. The Federal Labour Court decided that in October 2025, and Germany still has no transposition law.

The most consequential development in German equal pay law over the past year is not the Directive. It is one judgment, delivered before the transposition deadline passed, in a country that still has no transposition draft.

On 23 October 2025 the Bundesarbeitsgericht, Germany's Federal Labour Court, decided that a female department head who earned less than a male colleague in a comparable position could rely on that single comparison to establish the presumption of gender-based pay discrimination (8 AZR 300/24). The Landesarbeitsgericht, the regional labour court, had refused to allow a comparison with one individual and had held that the claim should be measured against the median pay of the male colleagues. The Federal Labour Court took a different view. The case went back to the Landesarbeitsgericht, where the employer now has the opportunity to rebut the presumption.

That procedural detail matters and is often lost in the summaries. The claimant has not won. What she has done is move the case to the stage where the employer must produce reasons, and the reasons have to be about her.

1. What the ruling changes in practice

Before the judgment, an employer facing a pay claim could argue about populations. Group averages, medians, distributions, and sample sizes were all available, and each of them dilutes an individual difference into a statistic.

After it, the first move belongs to the claimant, and it is a small one. She names one colleague of the other sex who does the same work or work of equal value and is paid more. On the Federal Labour Court's reading, that is enough to establish the presumption under § 22 AGG. The employer then has to demonstrate that this specific difference between these two specific people rests on objective, gender-neutral criteria.

The asymmetry is the point. Building the presumption costs the claimant one fact. Rebutting it costs the employer a documented history of how that pay was set.

The Directive pushes in the same direction from the other side. Under Article 18(2), an employer that has not met its transparency obligations bears the burden of proof without the claimant having to establish a prima facie case at all. Weak documentation is not only a weak defence, it removes the claimant's first step.

2. What actually has to be in the file

The rebuttal is a documentation exercise, and German courts have already ruled out several of the explanations employers reach for first.

Negotiation skill is not a defence. The Federal Labour Court held that in 2023 (8 AZR 450/21), and the reasoning is unchanged: a difference that exists only because one person negotiated harder is not an objective criterion. Salary history alone carries the same problem, and Article 5(2) of the Directive will in any case prohibit asking candidates about it. Personal circumstances such as marital status or maintenance obligations are not criteria. Neither is a difference that is simply inherited, for example where two workforces were merged and one side kept its historically higher pay without any current justification.

What is capable of working is narrower and more demanding than most pay files can support.

Two structural points follow from the way the criteria are framed. First, Article 4(4) of the Directive requires the assessment of equal value to rest on objective, gender-neutral criteria covering at least skills, effort, responsibility, and working conditions. Those four criteria are what a value group is built from, the Directive's own term for it being a category of workers. § 4 Abs. 2 EntgTranspG already works with an open “totality of factors” including the nature of the work, training requirements, and working conditions. German commentators expect the four criteria of the Directive to be read into that open wording by national courts before any transposition statute exists.

Second, each pay component has to stand on its own. Base salary, allowances, bonus, and special payments are each subject to the equal pay principle separately. Offsetting a lower base salary with a more generous bonus does not neutralise the base salary difference, it creates a second thing to explain.

3. How does an employee find out what one colleague earns?

This used to be the practical obstacle, and it is the part of the picture that changes fastest. Three routes are opening at once, and the one the employer used to control has stopped working.

The German information right does not deliver individual salaries. Under § 10 EntgTranspG an employee can ask for the comparison pay of employees of the other sex in a comparable activity, and § 11 Abs. 3 defines that figure as their statistical median, not their average. The right exists only in establishments with more than 200 employees (§ 12 Abs. 1). Article 7 of the Directive removes the size threshold, but it too stays at group level, there with average pay levels.

The second route is colleagues telling each other what they earn, and the clause that used to prevent it has largely stopped working. Clauses prohibiting employees from discussing their own pay are generally regarded as ineffective in Germany today, and Article 7(5) of the Directive requires Member States to prohibit them outright. Employers should expect individual salary figures to circulate in the workforce without being able to prevent it.

The third route runs through the courtroom. Article 20 of the Directive requires that national courts be able to order the disclosure of relevant evidence in the employer's control, including evidence containing confidential information, subject to measures protecting that information. The claimant does not have to arrive with the file. She has to arrive with a plausible case, and the court can compel the rest.

4. How far back does the money reach?

If the employer cannot rebut the presumption, the remedy is not symbolic. The difference is generally owed going forward and retrospectively, up to the point where the claim is time-barred, and non-material damages may be added.

Today that limit comes from general German civil law. There is no limitation rule in the Entgelttransparenzgesetz itself, so §§ 194 ff. BGB apply: a standard limitation period of three years under § 195 BGB, running from the end of the year in which the claim arose and the claimant knew or ought to have known the relevant circumstances (§ 199 Abs. 1 BGB).

Article 21(1) of the Directive sets a floor of three years for claims relating to the equal pay principle. Because German law already provides three years, several German practitioners take the view that this element changes little. That is a reasonable reading of the limitation period itself. It is not the whole of Article 21.

The Article also addresses when the clock starts and when it stops. Limitation periods are not to begin before the claimant is aware, or could reasonably be expected to be aware, of the infringement. Member States may provide that the period does not run while the infringement is continuing, or before the employment relationship ends. The period is also to be suspended or interrupted once the claimant takes action, whether by raising the matter with the employer or by bringing proceedings. That step may be taken directly or through workers' representatives, the labour inspectorate, or the equality body.

The provision most likely to matter in Germany is not a limitation period at all. Most German employment contracts and collective agreements contain forfeiture clauses, commonly requiring claims to be asserted within three months. Whether such a clause can extinguish an equal pay claim is contested, and practitioners are already advising that these clauses be reviewed. An employer whose defence depends on a three-month forfeiture clause is relying on the least settled part of the picture.

On the amount, Article 16 is explicit in a way German damages law usually is not. Compensation must provide full recovery of back pay and related bonuses or payments in kind, compensation for lost opportunities and for non-material damage, and interest on arrears. Member States may not fix an upper limit in advance.

5. Why none of this waits for the German statute

Germany missed the transposition deadline of 7 June 2026 and has published no draft. It would be a mistake to read that as a delay in exposure.

Equal pay between men and women is primary Union law under Article 157 TFEU, and it has been directly effective between private parties for decades. National courts are obliged to interpret national law in conformity with the Directive as far as possible, and that obligation carries more weight, not less, where the legislature has failed to act. Since June 2026, public sector employers, and bodies performing a public service under state supervision with special powers, can be held directly to those provisions of the Directive that are unconditional and sufficiently precise, without any national statute.

What a transposition statute is genuinely needed for is the machinery, meaning the reporting thresholds and deadlines, the authority the report goes to, the definition of workers' representatives, and the procedural rules that give Article 20 its force in a German court. None of that is required for an individual to bring a pair comparison to a German labour court, which is why the judgment of October 2025 arrived independently of the legislative timetable.

6. What to do about it

1. Write down how pay is set. Article 6 requires the criteria for pay levels and pay progression to be objective, gender-neutral, and easily accessible. An unwritten criterion cannot be produced in evidence.
2. Build the value groups before anyone asks. Group jobs on the Article 4(4) criteria of skills, effort, responsibility, and working conditions. Value groups assembled after a claim arrives look like they were assembled after a claim arrived.
3. Run the comparison the claimant would run. Look at pair comparisons inside each value group, not only at value group averages. A value group can show a 2 per cent average gap and contain a 15 per cent pair.
4. Document each pay decision when it is made. Name the criterion and the evidence for it. A justification reconstructed two years later is worth less than one recorded on the day.
5. Check each pay component separately. Base, allowances, bonus, and special payments each need their own gender-neutral basis.
6. Review the contract templates. Pay secrecy clauses are largely ineffective already. Forfeiture clauses are the next candidate.
7. Keep the evidence for longer than you think. Three years is a floor, and it may not start running until the worker could reasonably have known.

The reporting deadline is a date, and dates can be planned for. A pair comparison is not a date. It is available to any employee who knows what one colleague earns, in a legal environment that is making that increasingly easy to find out. Whether it succeeds turns on a question the employer answered years earlier, without knowing it was being asked: was the reason for this difference written down at the time, or is it being constructed now?
