# Refugee Law Lab: Canadian Legal Data

## Dataset Summary

The [Refugee Law Lab](https://refugeelab.ca) supports bulk open-access to Canadian legal data to facilitate research and advocacy. 
Bulk open-access helps avoid asymmetrical access-to-justice and amplification of marginalization that 
results when commercial actors leverage proprietary 
legal datasets for profit -- a particular concern in the border control setting.

The Canadian Legal Data dataset includes the unofficial text of legislation, regulations, and thousands of court and tribunal 
decisions at the federal level. It can be used for legal analytics (i.e. identifying patterns in legal 
decision-making), to test ML and NLP tools on a bilingual dataset of Canadian legal materials, and to 
pretrain language models for various tasks.


## Dataset Structure

### Data Instances

#### Court Decisions

- SCC: Full text of Supreme Court of Canada decisions, based on the Refugee Law Lab's
 [Supreme Court of Canada Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/scc/) (1877 – present) (updated Apr 1 2024)
- FCA: Full text of Federal Court of Appeal (Canada) decisions that have been given a neutral citation, based on the Refugee Law Lab's [Federal Court of Appeal Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/fca/) (2001-present) (updated Apr 1 2024)
- FC: Full text of Federal Court (Canada) decisions that have been given a neutral citation, based on the Refugee Law Lab's [Federal Court Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/fc/) (2001-present) (updated Apr 1 2024)
- TCC: Full text of Tax Court of Canada decisions that have been given a neutral citation, based on the Refugee Law Lab's [Tax Court of Canada Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/tcc/) (2003-present) (updated Apr 1 2024)

#### Tribunal Decisions

- CHRT: Full text of Canadian Human Rights Tribunal decisions, baed on the Refugee Law Lab's [Canadian Human Rights Tribunal Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/chrt/) (2013 – present) (updated Apr 1 2024)

- RAD: Full text of Immigration and Refugee Board, Refugee Appeal Division decisions, based on the Refugee Law Lab's [Refugee Appeal Division Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/rad/) (2013-present) (updated Apr 1 2024)

For more recent RPD decisions obtained via Access to Information Requests see the RLLR dataset.

- RLLR: Full text of Immigration and Refugee Board, Refugee Protection Division decisions, as reported in the [Refugee Law Lab Reporter](https://refugeelab.ca/rllr), based on the Refugee Law Lab's [RLLR Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/rllr/) (2019 – present) (updated Apr 1 2024)

- SST: Full text of Social Security Tribunal of Canada decisions, baed on the Refugee Law Lab's [Social Security Tribunal Bulk Decisions Dataset](https://refugeelab.ca/bulk-data/sst/) (2013 – present) (updated Apr 1 2024)

#### Legislation & Regulations

- LEGISLATION-FED: Text of Federal legislation in the [Consolidated Acts](https://laws-lois.justice.gc.ca/eng/acts/) maintained by the Federal Department of Justice, as reproduced in the Refugee Law Lab's [Federal Bulk Legislation Dataset](https://refugeelab.ca/bulk-data/legislation-fed/) (updated May 13 2024)

- REGULATIONS-FED: Text of Federal legislation in the [Consolidated Regulations](https://laws-lois.justice.gc.ca/eng/regulations/) maintained by the Federal Department of Justice, as reproduced in the Refugee Law Lab's [Federal Bulk Regulations Dataset](https://refugeelab.ca/bulk-data/regulations-fed/) (updated May 13 2024)


### Data Fields

- citation (string): Legal citation for the document (neutral citation where available)

- citation2 (string): For some documents multiple citations are available (e.g. for some periods
the Supreme Court of Canada provided both official reported citation and neutral citation)

- dataset (string): Name of the data instance (e.g. "SCC", "FCA", "FC", "TCC", etc)

- year (int32): Year of the document date, which can be useful for filtering

- name (string): Name of the document, typically the style of cause of cases and the short title for legislation and regulations

- language (string): Language of the document, "en" for English, "fr" for French, "" for no language specified

- document_date (string): Date of the document (yyyy-mm-dd)

- source_url (string): URL where the document was scraped and where the official version can be found

- scraped_timestamp (string): Date the document was scraped (yyyy-mm-dd)

- unofficial_text (string): Full text of the document (unofficial version, for official version see source_url)

- other (string): Field for additional metadata in JSON format, currently a blank string for most datasets

### Data Languages

Many documents are available in both English and French. Some are only available in one of the two languages.

### Data Splits

The data has not been split, so all files are in the train split. If splitting for training/validation, 
some thought should be given to whether it is necessary to limit to one language or to ensure that both
English and French versions of the same documents (where available) are put into the same split.

### Data Loading

To load all data instances:

```python
  from datasets import load_dataset
  dataset = load_dataset("refugee-law-lab/canadian-legal-data", split="train")
```

To load only a specific data instance, for example only the SCC data instance:

```python
  from datasets import load_dataset
  dataset = load_dataset("refugee-law-lab/canadian-legal-data", "SCC", split="train") 
```

## Dataset Creation

### Curation Rationale

The dataset includes all the [Bulk Legal Data](https://refugeelab.ca/bulk-data) made publicly available by 
the Refugee Law Lab. The Lab has focused on federal law and regulations, federal courts (e.g. Supreme Court of Canada, Federal Court of 
Appeal, Federal Court) and federal administrative tribunals (e.g. Immigration and Refugee Board) because 
immigration and refugee law, which is the main area of interest of the Lab, operates mostly at the federal level.

### Source Data

#### Initial Data Collection and Normalization

Details (including links to github repos with code) are available via links on the Refugee Law Lab's 
[Bulk Legal Data](https://refugeelab.ca/bulk-data/) page.

### Personal and Sensitive Information

Documents may include personal and sensitive information. All documents have been published online or 
otherwise released publicly by the relevant government body, court or tribunal. While the open court principle mandates 
that court (and some tribunal) materials be made available to the public, there are privacy risks when some of these 
materials become easily and widely available. These privacy risks are particularly acute for marginalized groups, 
including refugees and other non-citizens whose personal and sensitive information is included in some of the
documents in this dataset. For example, imagine a repressive government working with private data aggregators to 
collect information that is used to target families of political opponents who have sought asylum abroad.
One mechanism used to try to achieve a balance between the open court principle 
and privacy is that in publishing court documents in this dataset, the relevant courts and tribunals prohibit 
search engines from indexing the documents. Users of this data are required to do the same.

### Non-Official Versions

Documents included in this dataset are unofficial copies. For official versions published by 
the Government of Canada, please see the source URLs.

### Non-Affiliation / Endorsement

The reproduction of documents in this dataset was not done in affiliation with, or with the endorsement of 
the Government of Canada.

## Considerations for Using the Data

### Social Impact of Dataset

The Refugee Law Lab recognizes that this dataset -- and further research using the dataset -- raises challenging 
questions about how to balance protecting privacy, enhancing government transparency, addressing information 
asymmetries, and building technologies that leverage data to advance the rights and interests of 
refugees and other displaced people, as well as assisting those working with them (rather than technologies that 
[enhance the power of states](https://citizenlab.ca/2018/09/bots-at-the-gate-human-rights-analysis-automated-decision-making-in-canadas-immigration-refugee-system/) 
to control the movement of people across borders).

More broadly, the Refugee Law Lab also recognizes that considerations around privacy and data protection are complex 
and evolving. When working on migration, refugee law, data, technology and surveillance, we strive to foreground 
intersectional understandings of the systemic harms perpetuated against groups historically made marginalized. We 
encourage other users to do the same.

We also encourage users to try to avoid participating in building technologies that harm refugees and other 
marginalized groups, as well as to connect with [community organizations](https://www.migrationtechmonitor.com/ways-to-help) 
working in this space, and to [listen directly](https://www.migrationtechmonitor.com/about-us) and learn from people who are affected by new technologies. 

We will review the use these datasets periodically to examine whether continuing to publicly release these datasets achieves 
the Refugee Law Lab's goals of advancing the rights and interests of refugees and other marginalized groups without creating 
disproportionate risks and harms, including risks related to privacy and human rights.


### Discussion of Biases

The dataset reflects many biases present in legal decision-making, including biases based on race, immigration status, gender, sexual orientation, religion, disability, socio-economic class, and other intersecting categories of discrimination.

### Other Known Limitations

Legislation and regulations do not include tables, annexes or schedules. Original sources should be consulted if these are relevant.

Publicly available court and tribunal decisions are not a representative sample of legal decision-making -- and in some cases may reflect 
significantly skewed samples. To give one example, the vast majority of Federal Court judicial reviews of refugee determinations involve negative 
first instance decisions even thought most first instance decisions are positive (this occurs because the government seldom applies for judicial 
reviews of positive first instance decisions whereas claimants frequently apply for judicial review of negative decisions). As such, generative models
built partly on this dataset risk amplifying negative refugee decision-making (rather than more common positive refugee decision-making). 

Due to the ways that 
legal datasets may be skewed, users of this dataset are encouraged to collaborate with or consult domain experts.
