## Functions

### notifyOfArbitrationRequest

```solidity
function notifyOfArbitrationRequest(bytes32 question_id, address requester, uint256 max_previous) external
```

Notify the contract that the arbitrator has been paid for a question, freezing it pending their decision.

*The arbitrator contract is trusted to only call this if they've been paid, and tell us who paid them.*

**Parameters**

| Name          | Type    | Description                                                                                     |
| ------------- | ------- | ----------------------------------------------------------------------------------------------- |
| question\_id  | bytes32 | The ID of the question.                                                                         |
| requester     | address | The account that requested arbitration.                                                         |
| max\_previous | uint256 | If specified, reverts if a bond higher than this was submitted after you sent your transaction. |

### cancelArbitration

```solidity
function cancelArbitration(bytes32 question_id) external
```

Cancel a previously-requested arbitration and extend the timeout

*Useful when doing arbitration across chains that can't be requested atomically*

**Parameters**

| Name         | Type    | Description            |
| ------------ | ------- | ---------------------- |
| question\_id | bytes32 | The ID of the question |

### assignWinnerAndSubmitAnswerByArbitrator

```solidity
function assignWinnerAndSubmitAnswerByArbitrator(bytes32 question_id, bytes32 answer, address payee_if_wrong, bytes32 last_history_hash, bytes32 last_answer_or_commitment_id, address last_answerer) external
```

Submit the answer for a question, for use by the arbitrator, working out the appropriate winner based on the last answer details.

*Doesn't require (or allow) a bond.*

**Parameters**
