Of all functions in the esaj package, download_decision() is probably the simplest. Unlike lawsuit and query functions, there is only one decision function and absolutelly no helper functions are necessary; it simply downloads the PDF belonging to a decision.

It takes two arguments: a decision unique number (ID) and the path to a directory. It's important to note that the second argument isn't the path to a file like readr::write_*() functions expect, it's the path to a folder (which can, but not necessarily has to, exist).

As of this writing, download_decision() only works for São Paulo's Justice Court (TJSP).

Basic usage

To download a decision, simply call download_decision() with a decision ID and a path. The function will return the path to the downloaded PDF.

download_decision("10000034", "~/Desktop/")

This function is vectorized, meaning that we can pass it a character vector of IDs to download more than one decision.

download_decision(c("10800758", "10000034"), "~/Desktop/")

As expected, it returns the paths to both downloaded PDFs.

It's important to remember that download_decision() is breaking captchas in order to do its job (courtesey of the decryptr package). The function tries at most 10 times to break each captcha, so it's possible that it fails every time and isn't able to download the decision.

If you find it super necessary to download every single decision, we recommend using esaj:::download_decision_(). With this non-exported function one can force a larger number of attempts or even get a more verbose output from the execution.
