This article is for Irish business owners and startup founders who are setting up companies with co-founders or partners and want to avoid getting stuck in decision-making paralysis.
If you're wondering what happens when shareholders can't agree on critical decisions, or how to structure your company to prevent deadlock situations, this guide covers common deadlock scenarios, practical prevention mechanisms like casting votes and shotgun clauses, and what to include in your shareholder agreement to protect everyone involved.
Key Takeaways
• Avoid 50/50 shareholdings by using 51/49 or 60/40 splits to prevent deadlock without complex provisions.
• Include mandatory mediation clauses in shareholder agreements requiring 30-60 days of good faith negotiation before other remedies.
• Shotgun clauses force fair pricing but favor wealthier shareholders who can afford to buy out partners.
• Courts can order oppression remedies, forced buy-outs, or company winding up when deadlock makes operation impossible.
• Draft comprehensive shareholder agreements defining deadlock, resolution hierarchy, valuation mechanisms, and financing terms for forced purchases.

When Does Shareholder Deadlock Happen?
Deadlock occurs when shareholders cannot pass resolutions required to run the company effectively. This typically happens when voting power is evenly split or when special resolution thresholds cannot be met.
The company becomes paralysed, unable to make critical decisions about operations, strategy, or major transactions. This article explores common deadlock scenarios and how to avoid deadlock.
Common Deadlock Scenarios
The most problematic situations include:
- 50/50 shareholding where neither party can pass any resolution without the other's agreement
- Tied board votes when an even number of directors split evenly on important decisions
- Special resolution failure where minorities holding more than 25% block constitutional changes or capital actions
- Unanimous consent requirements in shareholder agreements that give any shareholder veto power
- Director appointment disputes preventing formation of a functioning board with proper quorum
What Does Your Constitution Say About Deadlock?
Most Irish private companies adopt standard constitutional provisions that provide limited deadlock protection. Understanding these default rules helps you identify where additional protections are needed.
Table A Default Provisions
The default Table A model constitution includes:
- Simple majority for ordinary resolutions requiring more than 50% of votes cast
- 75% threshold for special resolutions on constitutional changes and major actions
- One vote per ordinary share unless different classes specify otherwise
- Chairman's casting vote at board level in some circumstances
- No automatic deadlock resolution for shareholder-level disputes
These provisions work adequately when clear majorities exist but offer no help in genuine deadlock situations.
Constitutional Weaknesses
Standard constitutions fail to address several critical scenarios:
- Missing provisions for situations where directors cannot agree on fundamental business direction.
- No mechanism forcing resolution when shareholders reach permanent impasse on strategic decisions.
- Limited guidance on what happens when the company cannot function due to ongoing disagreement.
- Absence of buy-out provisions or fair valuation processes for exiting deadlocked situations.
How Can Casting Votes Break Deadlock?
Casting votes give specific individuals additional votes to break tied situations. This mechanism works best when an independent third party holds the casting vote power.
Board-Level Casting Votes
Many constitutions grant the board chairman a casting vote when directors tie. If four directors split 2-2 on a resolution, the chairman's casting vote determines the outcome.
This works only when the chairman doesn't have conflicts and commands respect from both sides. Problems arise when the chairman is appointed by one faction and lacks perceived independence.
Shareholder-Level Casting Votes
Casting votes can also operate at shareholder meeting level. The chairman of shareholder meetings might receive a second vote to break deadlock on resolutions.
Alternatively, an independent third party could hold shares carrying special voting rights activated only during deadlock.
What Role Does Mediation Play?
Mediation provides a structured negotiation process with an independent facilitator helping parties reach agreement. Unlike binding mechanisms, mediation preserves relationships while seeking mutually acceptable solutions.
Mandatory Mediation Clauses
Well-drafted shareholder agreements often require mediation before other remedies. Parties must participate in good faith mediation for a specified period (typically 30-60 days).
An agreed mediator or mediation organisation facilitates discussions about the disputed matter.
If mediation succeeds, parties document the agreed resolution and move forward. If mediation fails after the specified period, other deadlock mechanisms or court remedies become available.
Mediation Advantages and Limitations
Mediation offers several benefits:
- Lower cost than litigation or forced buy-outs
- Preserves business relationships where possible
- Flexible solutions not limited to legal remedies
- Confidential process protecting business privacy
- Faster resolution than court proceedings
However, mediation requires willing participants and cannot force outcomes on unwilling parties.
How Do Shotgun Clauses Work?
Shotgun clauses force resolution by requiring one shareholder to either buy the other's shares or sell their own shares. This mechanism works best in 50/50 ownership situations between two equal shareholders. When triggered, the shotgun clause operates as follows:
Shareholder A names a price at which they value all shares in the company.
Shareholder B chooses to either buy A's shares at that price or sell their shares to A at that price.
Transaction completes within specified timeframe (usually 30-90 days) according to the agreement terms.
One shareholder exits while the other acquires full ownership and control.
Why Shotgun Clauses Create Fairness
The mechanism incentivises realistic pricing through self-regulation:
If Shareholder A sets the price too low, Shareholder B will buy A's shares at that bargain price.
If Shareholder A sets the price too high, Shareholder B will sell their shares and take the windfall.
Shareholder A must therefore name a fair price they're genuinely willing to either pay or accept.
Shotgun Clause Risks
Despite their theoretical fairness, shotgun clauses create several practical problems:
- Financial inequality between shareholders means the wealthier party can force out the other regardless of merit.
- Financing pressure as respondents have limited time to secure funding for purchases.
- Business disruption from urgent deadlines forcing hasty decisions during already stressful situations.
- Strategic abuse when one party triggers the shotgun to exploit the other's temporary financial vulnerability.
Careful drafting can mitigate some risks through longer response periods, mandatory valuations, or restricted trigger timing.
What Court Remedies Exist?
When contractual mechanisms fail or don't exist, Irish courts provide several remedies for deadlocked companies. These court interventions represent expensive last resorts but remain necessary in extreme situations.
Oppression Petitions
Any shareholder can petition the court claiming company affairs are oppressive to their interests.
The court examines whether majority shareholders or directors acted unfairly toward the petitioner. Judges have wide discretion to fashion remedies that address the unfair conduct.
Common orders include requiring share purchases at fair values, changing company management, or altering governance structures.
Winding Up on Just and Equitable Grounds
Courts can order company winding up when deadlock makes continued operation impossible.
This drastic remedy applies when the company's main purpose can no longer be achieved. The court appoints a liquidator to sell assets and distribute proceeds to shareholders.
Winding up destroys business goodwill and usually realizes significantly less value than continued operation.
Court-Ordered Buy-Outs
Rather than destroying the company through winding up, courts often order one party to purchase the other's shares. The court determines fair value through independent valuation, often at considerable expense.
Payment terms can include instalments with security if the purchaser lacks immediate funds. The exiting shareholder receives cash while the remaining shareholder gains full control.
How Should You Structure Companies to Avoid Deadlock?
Prevention through proper initial structure proves far more effective than resolution after deadlock occurs. Strategic decisions about shareholding, board composition, and governance documents minimise deadlock risk. The simplest prevention measure is avoiding exactly equal shareholdings:
- 51/49 split gives one founder decision-making control while keeping the other heavily invested
- 60/40 split provides clearer control without completely marginalizing the minority
- Odd number of equal shareholders (three partners at 33.3% each) prevents exact splits
Even small differences create tiebreaking mechanisms without requiring complex provisions.
Include Comprehensive Shareholder Agreements
Well-drafted shareholder agreements should address deadlock explicitly:
- Define deadlock clearly specifying what situations constitute actual deadlock
- Establish resolution hierarchy (discussion, mediation, shotgun, court) with timeframes
- Set valuation mechanisms for buy-outs including independent valuers and formula approaches
- Specify financing terms for forced purchases including payment schedules
- Address ongoing obligations like non-competes and confidentiality after exits
Build in Independent Third Parties
Involving neutral parties from the start reduces deadlock risk. An independent non-executive director can cast deciding votes on board matters.
Professional advisors serving both parties can facilitate difficult discussions before positions harden. Advisory boards without formal authority sometimes help feuding founders reach compromise.
