Citizen Verifiability

31.3% · 3/8
DatapointScoreRationale & evidenceSource
4.1Public verification artifactDoes law mandate a downloadable public package containing certificates, device records, and result signatures?0.5/150.0%

Lithuania publishes election results, preliminary returns and audited party-finance statements on the Central Electoral Commission's website (§ 25, § 85, § 73), but there is no downloadable cryptographically-signed verification package with device records and result signatures.

4.2End-to-end verifiability permittedDoes law permit (or require) per-voter cryptographic receipts that prove inclusion without revealing the vote?0/50.0%

No matching sections in corpus (FTS returned 0 candidates) — concept not codified in this jurisdiction's election statute.

4.3Voter-verifiable paper trailIs voter-verifiable paper record (VVPAT or hand-marked paper) legally required?1/1100.0%

Lithuania votes by paper ballot — § 55 codifies the Central Electoral Committee's role in establishing the ballot-paper specimens, and § 5 of the Seimas Election Law mandates secret-ballot voting on paper.

specimens and forms of voter certificates, ballot papers, ballot paper envelopes and covering envelopes for voting by post

4.4Citizen re-tally rightCan any citizen — not just parties — legally re-tally from published precinct data?1/1100.0%

§ 73 (referendum) and § 85 (elections) require the Central Electoral Committee to publish results in the Valstybės žinios Official Gazette within statutory deadlines, and § 25 of the Funding Law posts financial statements on the CEC website — any citizen has the data needed to re-tally.

Custody Hardware

DatapointScoreRationale & evidenceSource
2.1Hardware tamper standardAre tamper-evident or tamper-responsive hardware standards mandated?2/540.0%

§ 51 (referendums) and the parallel Seimas-law provisions require the polling-district committee to verify each ballot box is empty and seal it before voting starts, with sealed ballot transfer to the constituency committee for counting. Tamper-evident seals; level 2.

2.2Network isolation mandateIs internet/Wi-Fi/cellular connectivity legally prohibited on vote-casting equipment?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: FTS surfaced results-publication provisions; Lithuania's vote-counting is by hand in the polling-district committee, so there is no vote-casting equipment with network connectivity — but the absence is implicit rather than a codified prohibition.

§ view source
2026-05-23
2.3Custody documentationIs full chain-of-custody documentation required and publicly available?0.5/150.0%

§ 75 and § 77 codify sealed-box opening and counting in the presence of the polling-district committee, with the counting record drawn up and signed, and § 1-303-style retention follows; the surfaced section addresses voter-list updates rather than ballot custody, so chain-of-custody documentation is codified piecemeal across the act.

Post Election Audit

5.6% · 1/9
DatapointScoreRationale & evidenceSource
3.1Mandatory auditIs a post-election audit legally required for every election?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: § 24 of the Funding Law mandates an independent financial audit of political parties and campaigns, but Lithuania does not codify a post-election audit of vote-counting equipment — vote counting is by hand in the polling-district committee, so there is no separate machine audit to mandate.

§ view source
2026-05-23
3.2Audit methodWhat audit method is mandated?0/50.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: Lithuania has no codified vote-counting audit method — the polling-district committee hand-counts paper ballots and signs the vote-counting record (§ 75, § 77, § 82); the surfaced § 24 mandates audit of party finances, not vote tabulation.

§ view source
2026-05-23
3.3Audit triggers beyond mandatoryDoes law trigger additional audits on close margins or sworn challenges?0/10.0%

No matching sections in corpus (FTS returned 0 candidates) — concept not codified in this jurisdiction's election statute.

no FTS match
2026-05-23
3.4Public observation of auditAre parties, media, and citizens granted observer access to the audit?0.5/150.0%

§ 25 of the Funding Law requires the Central Electoral Commission to post audited financial statements and the auditor's findings on its website, and vote counting itself is observable by election observers and the media (§ 83); there is no separate post-election vote audit whose observation needs codifying.

§ view source
2026-05-23
3.5Binding forceAre audit results legally binding on the final certified result?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: Lithuania has no codified post-election vote audit, so there is no audit-binding-on-result rule; § 25 governs publication of the (binding) party-finance audit.

Software Verifiability

0.0% · 0/9
DatapointScoreRationale & evidenceSource
1.1Source code disclosureIs voting system source code legally accessible?0/50.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: FTS surfaced candidate-collaboration disclosure provisions; Lithuania votes on paper at polling stations with no voting-machine software, so there is no voting-system source code to disclose.

1.2Reproducible builds requirementMust the binary that runs in production be reproducibly buildable from public source?0/10.0%

1.3Pre-election binary commitmentIs the running binary cryptographically committed (hash published) before polls open?0/10.0%

No matching sections in corpus (FTS returned 0 candidates) — concept not codified in this jurisdiction's election statute.

no FTS match
2026-05-23
1.4Election definition publicationAre ballot contests, layouts, and tabulation rules signed and published before polls open?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: FTS surfaced election definitions; Lithuania publishes ballot specimens, envelopes and seals through the Central Electoral Committee (§ 55 Seimas Election Law), but the ballot designs and tabulation rules are not signed or cryptographically committed before polls open.

§ view source
2026-05-23
1.5Post-election integrity checkDoes law grant a right to verify the actual running binary matches the committed one?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: There is no voting-system software in Lithuania (paper ballots, hand counting), so no codified post-election software-integrity check exists; § 23 of the Funding Law governs the audit of party-finance, not voting equipment.

6.1Domestic observer rightsAre party and civil-society observers given full procedural access?1/1100.0%

§ 83 entitles party and civil-society election observers, and mass-media representatives, to participate in vote counting at polling-district and municipal levels and in the establishment of results; § 59/§ 61 codify the observers' general access right.

6.2International observer accessAre OSCE/EU/IFES international observers admitted by default?0.5/150.0%

Lithuania's election and referendum observer frameworks (§ 49 Referendum Law, § 61 Seimas Law) recognise observers appointed by parties and groups, and the country routinely admits OSCE/ODIHR missions in practice, but the statute does not specifically name international observers.

2026-05-23
6.3Precinct-level results publication speedAre precinct-level results legally required to be published within 24h of poll close?4/580.0%

§ 85 has the Central Electoral Committee proclaim preliminary results to the mass media immediately as constituencies deliver their counts, and § 73 requires final referendum results in the Valstybės žinios within 4 days. Within 48 hours; level 4.

Preliminary election results may be proclaimed only by the Central Electoral Committee

5.3Contract duration capAre vendor contracts capped in duration, preventing perpetual lock-in?0/10.0%

No section in the FTS-surfaced candidates satisfies this criterion. Best signal: Lithuania has no voting-system vendor contracts to cap — voting is by paper ballot with hand counting; the surfaced § 24 governs financial-audit contracts.

7.1Ballot secrecy guaranteeIs voter–ballot unlinkability legally guaranteed and enforceable?1/1100.0%

§ 5 of the Seimas Election Law (and § 6, § 2 of the Referendum Law) guarantees the secret ballot — voters vote in person and by secret ballot, and voting by proxy is prohibited.

Voters shall vote in person and by secret ballot.

7.2Accessibility mandateAre accessibility standards (vision, motor, language) legally required at every polling place?3/560.0%

§ 5 (Secret Ballot) permits a voter unable to cast a ballot personally because of physical disability to vote with the assistance of a person they trust, and § 71 codifies voting in medical-treatment and social-care facilities; Lithuania does not codify comprehensive ADA-style polling-place accessibility standards. Level 3.

At least 25 days before the election, a polling district committee, a diplomatic mission shall provide conditions for the voters to have access to voter lists.

7.3Polling-place density floorIs there a legal floor on polling places per N voters or per geographic area?0.5/150.0%

§ 11 of the Seimas Election Law governs the formation of polling districts and § 71 codifies special polling stations in medical and social-care facilities, but a specific statutory polling-place-per-N-voters floor is not codified.
