The lawsuit between Ripple Labs and the U.S. Securities and Exchange Committee, or SEC, at present involves major crypto substitution Binance after a recent filing on behalf of Ripple CEO Brad Garlinghouse.

According to court documents filed in the Southern Commune of New York on Monday, Garlinghouse's legal team has requested documents "relevant to the case and unobtainable through other means" from Binance Holdings Limited, the Cayman Islands-based subsidiary of the major cryptocurrency exchange. The filing cited U.Southward. laws concerning the Department of State and the Hague Convention and asked the court to result a letter of request for the Central Authorization of the Cayman Island to compel testify from Binance.

"Mr. Garlinghouse seeks foreign discovery on the ground of his good religion belief that [Binance Holdings Limited] possesses unique documents and data apropos this case, and specifically, concerning the process past which transactions in XRP allegedly conducted by Mr. Garlinghouse on strange digital asset trading platforms were conducted," said the filing.

Specifically, the lawyers seem to be challenging claims from the SEC that the Ripple CEO sold more than 357 million XRP tokens on "worldwide" crypto trading platforms to investors "all over the earth." The team cited Section V of the Securities Act of 1933, stating the alleged illegal XRP sales applied only to domestic sales and offers of securities. The documents requested of Binance may contain evidence in support of that claim.

"As the SEC knows, Mr. Garlinghouse's sales of XRP were overwhelmingly made on digital asset trading platforms outside of the United States [...] the discovery that Mr. Garlinghouse seeks volition be relevant to demonstrating that the offers and sales that the SEC challenges did not occur in this land and are not subject field to the law that the SEC has invoked in this example."

The request is part of a lawsuit the SEC filed confronting Ripple in December, alleging the firm, Garlinghouse and co-founder Chris Larsen had been conducting an "unregistered, ongoing digital asset securities offer" with their XRP token sales. Ripple's legal squad had previously claimed that XRP is more like Bitcoin (BTC) or Ether (ETH) — which the regulatory body has classified as bolt rather than securities.

Even so, the firm seems to be switching gears — or trying to augment its case — by challenging allegations of domestic versus international token sales. Garlinghouse and Larsen filed a motility in June petitioning international government to request documents from several non-U.S.-based crypto exchanges including Bitstamp, Huobi, and Upbit. The case will reportedly finish the pre-trial discovery process on October. 15.
