esaj R package is a simple interface that allows you to download multiple kinds of files from Brazil's e-SAJ (Electronic Justice Automation System) portals. With this package you can save and parse lawsuits, queries, and decisions with very simple, tidyverse compliant functions.
esaj, run the code below:
# install.packages("devtools") devtools::install_github("courtsbr/esaj")
esaj if you wanted to gather information about lawsuits being processed by Brazil's state-level Judiciary, you would have to go to each state's e-SAJ portal, manually input each lawsuit's ID, break a capthca, and only then download an HTML with the information you wanted; now you can simply run
download_cposg(), and spend your valuable time analysing the data.
# Download first degree lawsuits from multiple states ids <- c( "0123479-07.2012.8.26.0100", "0552486-62.2015.8.05.0001", "0303349-44.2014.8.24.0020") esaj::download_cpopg(ids, "~/Desktop/") #>  "/Users/ctlente/Desktop/01234790720128260100.html" #>  "/Users/ctlente/Desktop/05524866220158050001.html" #>  "/Users/ctlente/Desktop/03033494420148240020.html" # Download second degree lawsuits from São Paulo ids <- c( "1001869-51.2017.8.26.0562", "1001214-07.2016.8.26.0565") esaj::download_cposg(ids, "~/Desktop/") #>  "/Users/ctlente/Desktop/10018695120178260562.html" #>  "/Users/ctlente/Desktop/10012140720168260565.html"

Besides downloading lawsuits (see the Downloading Lawsuits article),
esaj also allows the user to download the results of a query on lawsuits. This kind of query is very useful for finding out what lawsuits contain certain words, were filed in a given period, were filed in a given court, etc.
# Download results of a simple first degree query esaj::download_cjpg("recurso", "~/Desktop/") #>  "/Users/ctlente/Desktop/search.html" #>  "/Users/ctlente/Desktop/page1.html" # Download results of a slightly more complex second degree query esaj::download_cjsg("recurso", "~/Desktop/", classes = c("1231", "1232")) #>  "/Users/ctlente/Desktop/search.html" #>  "/Users/ctlente/Desktop/page1.html"
For more information on how to use these functions and all their auxiliary methods (like
cj*g_table()), please see Downloading Queries.
Of all functions in the
download_decision() is probably the simplest: it downloads the PDF belonging to a decision and that's it.
# Download one decision esaj::download_decision("10000034", "~/Desktop/") #>  "/Users/ctlente/Desktop/10000034.pdf" # Download more than one decision esaj::download_decision(c("10800758", "10000034"), "~/Desktop/") #>  "/Users/ctlente/Desktop/10800758.pdf" #>  "/Users/ctlente/Desktop/10000034.pdf"
